Set Up and Configuration

Communications Set-Up

This is where the thermostat address is entered. Additionally, the total number of thermostats (or the highest addressed stat on the network) is entered here to optimize communication timing. Consult a qualified service technician before changing any of the values in this Sub-Menu (Sub-Menu not shown).

Temperature Set-Up

The first and second stage differentials can be changed, as can the display temperature offset. The differentials set the tightness of the temperature control. If the equipment is operating too often, or the temperature swings are uncomfortably large, the differentials can be increased or decreased respectively. The temperature offset (calibration) allows the user to “customize” the temperature shown on the display. Consult a qualified HVAC service technician before changing any of the values in this Sub-Menu (Sub-Menu not shown).

Temperature Control Options

OFFSET

Allows the user to offset the displayed room temperature ±3°F from true tem-

 

perature. This thermostat is calibrated to be within ±1°F of true temperature.

 

 

1ST STAGE DIFFERENTIAL

Determines the level of control and consequently the cycle rate. Adjustable

 

between 0.5°F and 2.0°F, this is the value above/below the set point that the

 

temperature must rise (fall) to start the cooling (heating). It is also the value

 

below (above) the set point that the temperature must fall (rise) for the cooling

 

(heating) to stop. For example, if the temperature setting was 70°F and the 1st

 

stage differential was set at 0.5°F, in the heat mode the heat would come on at

 

69.5°F and stay until the temperature was 70.5°F. A small differential will result

 

in a tighter control, but more heating/cooling cycles.

 

 

2ND STAGE DIFFERENTIAL

Again adjustable between 0.5°F and 2.0°F, this also determines the level of

 

control by determining when to use the 2nd stage of heating or cooling. It can

 

also be used to keep 2nd stage cooling from coming on too soon when 1st

 

stage is acting to control temperature levels or to keep costly auxiliary heat

 

from coming on too soon when the heat pump is sufficient.

 

 

Backlighting Set-Up

Both displays have backlighting which can be controlled in three ways (FIG. 37). First, backlighting can be turned on every time a button is pushed. Second, it can be configured to come on with a button push, but only when the ambient light is below a preset value. When “only when needed” is selected, the user can select from two levels of ambient light. Finally, it can be disabled.
