INSTALLER

INFORMATION / ADVANCED FEATURES

SAFETY CONSIDERATIONS

Improper wiring or installation may damage controller. Wiring must conform to local and national electrical codes

INTRODUCTION

The controller is a wall mounted, 24VAC low-voltage controller which maintains room temperature by controlling the operation of a heating and air conditioning system. Batteries are not required; temperature and mode settings are preserved with the power off.

INSTALLATION CONSIDERATIONS

The controller requires no batteries. The controller is not a power stealing device and MUST have both R and C connected.

INSTALLATION

IV. CONTROLLER LOCATION

Controller should be mounted:

-Approximately 5 ft. (1.5m) from floor.

-Close to or in a frequently used room, preferably on an inside partitioning wall.

-On a section of wall without pipes or duct work.

Controller should NOT be mounted:

-Close to a window, on an outside wall, or next to a door leading to the outside.

-Exposed to direct light and heat from a lamp, sun, fireplace, or other temperature-radiating object which may cause a false reading.

-Close to or in direct airflow from supply registers and return-air grilles.

-In areas with poor air circulation, such as behind a door or in an alcove.

V. INSTALL CONTROLLER

1.Turn off all power to unit.

2.If an existing thermostat is being replaced:

A.Remove existing thermostat from wall.

B.Disconnect wires from existing thermostat, one at a time. Be careful not to allow wires to fall back into the wall.

C.As each wire is disconnected, record wire color and terminal marking.

D.Discard or recycle old thermostat.

NOTE: Mercury is a hazardous waste and MUST be disposed of properly.

3.Separate the front and back pieces of plastic.

4.Route thermostat wires through hole in back piece of plastic. Level plastic against wall (for aesthetic value only - thermostat need not be leveled for proper operation) and mark wall through 2 mounting holes.

5.Drill two 3/16-in. mounting holes in wall where marked.

6.Secure back plastic to wall with 2 anchors and screws provided making sure all wires extend through hole in plastic.

7.Use minimum of 22-gauge wiring, 18-gauge is recommended, for basic controller wiring. Shielded twisted pair should be used for optional remote indoor and outdoor sensors. Connect wires to proper terminal of the connector block in the front plastic.

8.Push any excess wire back into wall. Excess wire inside the controller plastic case can interfere with proper air flow across the temperature sensor. Seal hole in wall to prevent air leaks. Leaks can affect operation.

9.Snap front and back pieces of plastic together.

10.Turn on power to the unit.

VI. INSTALLER SETTINGS

NOTE: These options are intended to be used by the installer. End users are not advised to change or modify any of these settings. Doing so may make your equipment stop working properly and/or may void the warranty of the controller as well as the equipment hooked up to the controller. To access the installer setting menu, the mode must be set to OFF. Then, press both the up and down arrows keys at the same time for at least 5 seconds to enter the installer screen.

MODEL CONFIGURATION

Options to select from:

HEAT COOL/HEAT PUMP,

SINGLE STAGE/MULTI STAGE,

ECONOMIZER/NO ECONOMIZER

CS2000A INSTALLED..YES OR NO

PROGRAMMABLE/NONPROGRAMMABLE

BOLD items are default

NOTE: - If CS2000A is installed, the controller will inhibit all outputs except the Y0/D when there is no 24Vac applied to the L input on the thermostat. When the CS2000A is not installed, the L input is the Lock out signal from the heat pump.

ACCESSORIES

Each of these options has settings for Cumulative Run Time and Calendar Time. Messages will flash at the top of the Main screen when these events are met to alert the owner that it is time service these options.

Air Filter - Cumulative Run Time default is 1000 hours and Calendar Time is 3 months. Values can range from 400-3600 hours for Cumulative Run Time (in 100 hour increments), or Calendar Time can be set to OFF, or 1-48 months (in 1 month increments).

Humidifier - Cumulative Run Time default is 0 hours (OFF) and Calendar Time is OFF. Values can range from 400-3600 hours for Cumulative Run Time (in 100 hour increments), or Calendar Time can be set to OFF, or 1-24 months (in 1 month increments).

UV Lamp - Cumulative Run Time default is 0 hours (OFF) and Calendar Time is OFF. Values can range from 400-12000 hours for Cumulative Run Time (in 100 hour increments), or Calendar Time can be set to OFF, or 1-48 months (in 1 month increments).

Air Cleaner - Cumulative Run Time default is 0 hours (OFF) and Calendar Time is OFF. Values can range from 400-3600 hours for Cumulative Run Time (in 100 hour increments), or Calendar Time can be set to OFF, or 1-24 months (in 1 month increments).

INPUT DEALER INFO

Contractors are able to input Brand Name, Unit Model Number, Contractor Name, and Contractor Phone number into these screens. This way, the owner could give this information to the contractor so that he would know what system the owner has prior to the service visit.
