INSTALLATION
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION.
C A U T I O N :
This thermostat is protected against normal static electric
discharges. However, in extremely dry weather you should touch
a grounded metal object before touching the thermostat to
minimize the risk of causing damage to the unit.
TOOLS REQUIRED:
•#1 Phillips screwdriver (small - medium)
•Drill with 3/16-in. (4.8mm) drill bit
•Wire stripper/cutter
3.Take note the letters printed near the wire terminals. Attach labels (enclosed) to each wire for identification by terminal letter, not color.
4.Make sure the wires do not fall back inside the wall, and remove and label one wire at a time. Do not allow wires to touch each other or any parts of the thermostat.
5.Loosen all screws on the old thermostat and/or base, and remove it from the wall.
C A U T I O N :
Be careful not to drop the body or disturb any
of the electronic parts.
MOUNTING THE NEW THERMOSTAT:
1.Strip insulation leaving 3/8 in. (9.5mm) of bare wire on the ends and clean off any corrosion present.
2.Fill the wall opening with non-combustible insulation to prevent drafts from affecting the thermostat while in use.
3.Pull your new thermostat apart by applying pressure to the thumb tab on the bottom edge of the unit. While pressure is being applied to this release latch, pull the two halves of the thermostat apart near the bottom edge.
4.Hold the base against the wall. Route the wires through the larger hole adjacent to the terminal block. Position the base for best appearance (to hide any marks from an old thermostat). Attach the base to the wall with the two screws provided.
NOTE: If you are mounting the base to a soft material like plasterboard, or if you are using the old mounting holes, the screws may not hold. Drill a 3/16-in (4.8mm) hole at each screw location, and insert the plastic anchors provided. Then mount the base as described below.
CONNECTING THE WIRES:
5. Clean bare wire ends must be inserted between the black clamp plate and the brass terminal as shown here.
6. Securely tighten all electrical terminal screws (even unused ones).
WIRING INFORMATION
**Complete heating or cooling system wiring can be found in the WIRE IDENTIFICATION AND WIRING SCHEMATICS section of this instruction sheet. The schematics shown provide component information for brand new installations or for un-referenced wires.
SETUP OPTIONS
A table similar to this one shown below is printed on the thermostat's circuit board. There may be minor differences present in some of the wording of your specific model, but the function of each option will be the same.
| UP | DOWN |
JP1 (SCALE) | F | C |
JP2 (FAN) | ELECT | GAS |
JP3 (B / O) | B | O |
JUMPER SETTINGS:
There are three (3) headers (or jumpers) located inside the thermostat at the rear of the circuit board. These settings can be changed from their default values by removing its corresponding black jumper cap and reinstalling the cap so that it is positioned on the adjacent pair of metal pins. A change to ANY of the jumper settings will not be recognized until power to the thermostat is removed for at least 2 minutes, and then power is restored again. This can simply be accomplished by removing the thermostat from the wired back plate. Each of these jumpers changes a different setup option. The choices for these options are listed in a table printed on the circuit board, and are also printed adjacent to each individual setting jumper.
| | F |
JP1 - FAHRENHEIT OR CELSIUS DISPLAY FORMAT: | | | JP1 |
This setting controls whether the temperature is shown in | | |
degrees °F or °C on the LCD display screen. | | | |
| | | |
JP2 - GAS / ELECTRIC FAN OPERATION: | | C |
| | ELECT |
This setting changes whether the system's blower fan (if | | |
| |
applicable) is controlled by the thermostat in HEAT mode. | | | |
Choose ELECTRIC if you have electric heating, and | | | |
| | |
require the thermostat to control the fan. Choose GAS if | | | GAS |
you have a gas heating system, this will allow the furnace | JP2 |
itself to control the operation of the blower fan. |
NOTE: If you have an Electric Heat system and the blower does not operate after installation, locate the "Gas/Electric" option jumper and ensure that it is in the "Electric" position.
FRONT PANEL ITEMS
SYSTEM MODE SWITCH:
The MODE switch has three positions: HEAT, OFF, and COOL. In the winter, set the mode switch to HEAT to control your heating system; in the summer, set the switch to COOL to control your air conditioning. In the spring and fall, or when the windows are open, you can set the switch OFF.
NOTE: When the system mode switch is in the OFF position, it is normal for the system's blower fan ("G" terminal if used) to still become activated depending upon the position of the FAN mode switch (see below).
FAN MODE SWITCH:
The FAN switch has two positions: AUTO and ON.
•In the AUTO position, the operation of the blower fan is determined only by the on/off cycling of the heating and cooling systems.
•When the FAN switch is in the ON position, the system's blower fan will be commanded ON, and remain ON while the FAN switch is in the ON position (this also includes when the System Mode Switch is in the OFF position).
NOTE: The FAN switch only works if your system provides a wire for the thermostat’s "G" terminal.
PUSH BUTTONS:
There are two push buttons to the right of the unit's display screen. These are used to adjust the set point temperature.
OPERATING INSTRUCTIONS
TEMPERATURE ADJUSTMENT:
While in HEAT or COOL mode, a single press on either the UP or DOWN button causes the word “SET” to appear on the screen. Once “SET” is present, the set temperature value starts flashing and the set point temperature can be altered by pressing either the UP or DOWN button once per degree of change, or by holding either button for at least two seconds to automatically increment the set point quickly in the associated direction.
Based upon the relationship of the set temperature to the displayed ambient room temperature, the thermostat will engage either the W1 terminal in heat mode or the Y1 terminal in cool mode, if a temperature demand is present.
(For the PSD022W model only):
If there is a large thermal demand present which is greater than the first stage of heating (W1) or cooling (Y1) can accommodate for, then a second stage of heating (W2) or cooling (Y2) will be activated. When the second stage of either heating or cooling becomes active, the word “AUX” will be shown on the display screen. There is approximately a 4 minute delay that is enforced between the activation of the first stage and the second stage of heating or cooling.
DISPLAY ILLUMINATION:
Pressing either set temperature button will illuminate the display for easier viewing in dim light conditions. The light will remain on for approximately 12 seconds. While the light is illuminated, pressing any of the three push buttons will continue the lighting and remain on for approximately 12 more seconds.
MINIMUM RUN/OFF TIME:
This is determined by the thermostat, and controls the minimum length of time that the thermostat must remain with Heat or Cool either On or Off, before it will automatically switch to the alternate On or Off state. This feature prevents rapid or short cycling, and provides compressor protection for cooling equipment. The time amount for this delay is fixed at 5 minutes between on or off load changes.
TEMPERATURE LIMIT STOPS (PSD011Ba ONLY):
There are two independent set temperature stops: a Maximum Heat Set Temperature, and a Minimum Cool Set Temperature. Each of these temperature stops is user adjustable in one-degree increments. The heat limit stop prevents the set temperature from being adjusted higher than the heat limit setting. The cool limit stop prevents the set temperature from being adjusted lower than the cool limit setting.
To set the heat and cool set temperature limit stops, always start with the system mode switch in the OFF position. Press and hold the UP key while sliding the mode switch from either OFF to HEAT (to adjust the maximum heat set temperature), or from OFF to COOL (to adjust the minimum cool set temperature). “Ht Lim” or “Cl Lim” will be displayed on the LCD screen while you are setting the heat or cool limits respectively. While in the adjustment mode for each of the temperature stops, use the UP and DOWN buttons to adjust the limit value, just as you would for adjusting the set temperature under normal operation. NOTE: If no buttons are pressed for 4 seconds, the thermostat will accept the limit value that was on the screen, and return to normal operating mode, for the current mode switch position. Once, complete, you should return to the adjustment mode again for both heat and cool to confirm your desired settings for both temperature modes.
TECHNICAL ASSISTANCE
C A U T I O N :
Turn off electricity to the appliance before
installing or servicing the thermostat or any part of the system. Do not turn the electricity back on until the work is completed.
•Your thermostat is a precision instrument. Please handle it with care.
•Do not short (jumper) across the electric terminals on either the furnace or air conditioner to test the system. This may damage the thermostat and void your warranty.
•All wiring must conform to all applicable local codes and ordinances.
•This thermostat should be limited to a maximum of 1.5 amps; higher current may cause damage to the thermostat.
THERMOSTAT LOCATION:
On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new instal- lations, follow the guidelines listed below.
1.Locate the thermostat on an inside wall, at about 5 ft. (1.5m) above the floor, and in a room that is used often.
2.Do not install it where there are unusual heating conditions, such as: direct sunlight, near a lamp, television, radiator, register, fireplace, on a wall opposite a stove, or that carries hot water pipes.
3.Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room, or in a draft from a stairwell, door, or window.
4.Do not locate where air circulation is poor, such as: in a corner or alcove, or behind an open door.
5.Do not locate in a damp area. This can lead to corrosion that may shorten thermostat life.
6.Do not install the unit until all construction work and painting has been completed.
REMOVING THE OLD THERMOSTAT:
1.Switch OFF the electricity to both the furnace and air conditioner; then proceed with the following:
2.Remove cover from old thermostat. Most are snap-on types and simply pull off, some have screws on the sides, and these must be loosened first.
JP3 - [B] OR [O] TERMINAL USAGE OPTION: | | |
This setting determines how the thermostat will use the | | B |
shared B/O terminal connection on the back plate. Choose | | |
the UP (B) position to have the B/O terminal powered | JP3 | |
while in heat mode, and un-powered while in cool and off | |
modes. Choose the DOWN (O) position to have the B/O | | |
terminal powered while in cool mode, and un-powered | | |
| O |
while in heat and off modes. | |
COMPLETING THE INSTALLATION
Once any optional jumper settings have been performed as described in the previous section, ensure that at least 2 minutes have passed since the thermostat has been last powered. Install your new thermostat onto its base. To do this, start with the bottom tilted out towards you at first, and line up the two holes in the top of the thermostat with the two hooks on the top of the back plate. Slowly pivot the bottom of the thermostat towards the back plate and push firmly on the bottom half of the thermostat until it is securely latched to the back plate. If the two thermostat halves do not latch easily, remove and try again. Do not attempt to force them together.
NOTE: Before use, remove the plastic film (if present) that is protecting the LCD display screen.
Turn the electrical power back ON to both your heating and/or air conditioning systems. Verify that both systems (and the blower fan if used) are operating properly. When set to a high temperature, the heating system should provide warm air after a short time in Heat Mode. Likewise, a cooling system should provide cool air after a short time when set to a low temperature in Cool Mode. Usually, sound from the furnace and/or air conditioning units can be heard while either is running. If your system uses a blower fan, the rush of moving air should be heard within a short time after either has been started. Your installation is now complete.
