If a value of 105 to 110 is selected (second-stage heating is turned off at this value) then the first-stage high temperature trip limit is the programmed value plus 5°F (first-stage is turned off).

If a value of 111 to 155 is selected (second-stage heating is turned off) then the first-stage high temperature trip limit is the programmed value plus 20°F (first stage is turned off).

Example 1:

High temperature trip limit selected is 105°F. (Shown as 05 in controller display.)

Second-stage heat will turn off when duct temperature sensor measures a temperature greater than 105°F.

First-stage heat will turn off when duct temperature sensor measures a temperature greater than 110°F.

Example 2: High temperature trip limit selected is 140°F. (Shown as 40 in controller display.)

Second-stage heat will turn off when duct temperature sensor measures a temperature greater than 140°F.

First-stage heat will turn off when duct temperature sensor measures a temperature greater than 160°F.

7.Dual Fuel Setpoint (S-7)

This option is used with a system that has a heat pump and another heat source (possibly gas) that should not run at the same time as heat pump. When any heat pump is on, all auxiliary heat will be off, and vice versa.

NOTE: The auxiliary heat must always have greater heating ability than the heat pump at low outdoor temperatures for this option to have any value.

NOTE: If Dual Fuel setpoint is set to 0, then this option is disabled. If Dual Fuel option is used, an outside air temperature sensor or refrigerated air sensor must be used.

When dual fuel setpoint variable is set to outdoor temperature (10°F to 60°F) that is the crossover point between running heat pump or using auxiliary heat as the preferred method of heating.

The setpoint is used only when the first stage of heating is brought on. If outdoor temperature is above setpoint, heat pump (Y1) is energized. If outdoor temperature is below setpoint, auxiliary heat (W1) is used. If heat pump is started and outdoor temperature goes below setpoint, dual fuel option is not used for that heating cycle.

PROGRAMMABLE OPTIONS-TOGGLES

Turn zone selector dial to position T. (See Fig. 18.) The controller display shows setting number and its value.

The upper left 2 digits show setting number while the right side shows the value of ON or OFF.

Press the COOL up or down setpoint buttons to change toggle number and the HEAT up or down setpoint buttons to change status of toggle. (See Table 11.)

Step 12ÐWiring Diagrams

Refer to Tables 7 and 8 for wiring diagram reference information.

Step 13ÐStart-Up

1.Verify that zone number for remote room sensors and corre- sponding zone damper wire connections are the same in the Comfort Zone Center.

2.Check that AC power wires (dampers and transformer) are kept away from DC wires (remote room sensors, 4 zone controller, communication bus) leading up to, and in the Comfort Zone Center.

3.Check location of 4 zone controller and remote room sensors to make sure that they are not near heat producing devices such as lamps, sunlight, and appliances.

4.Make sure that the 3 wire communication bus cable for the 4 zone controller is not run in same conduit, or use same cable jacket, as the 5 wire conductor of the 4 zone controller.

5.On a remote room sensor follow wire guide stamped on base by terminal screws in order to keep polarity and voltages correct. Otherwise sensor will not work properly.

6.Make sure duct temperature sensor is placed in supply air duct work, downstream of furnace and evaporator coil, and up- stream of bypass damper.
