INSTALLER CONFIGURATION (cont.)
To exit the menu at any time, press
PROGRAM RUN .
MULTI-STAGE/HEAT PUMP MODE.
(Installer table step 1.) Use this item to select the system type (multi- stage or heat pump). IF YOU HAVE A HEAT PUMP SYSTEM, you must select HEAT PUMP here. This sets up proper default values for most heat pump systems. This selection also makes available some additional menu items that apply only to heat pump systems.
HEAT PUMP COMPRES- SOR CONFIGURATION.
(Installer table step 2; this menu item is displayed only when heat pump was selected in step 1.) Use
this item to select the number of heat pump compressors and how they are connected.
ELECTRIC HEAT FAN CONFIGURATION.
(Installer table step 3.) This menu item determines whether fan control will be through the thermostat or through the heating system. If you have an electric heat or other system that REQUIRES the thermostat to control the fan, set this item ON. This allows the thermostat to energize the fan immediately on a call for heat. If you are unsure if the system requires the thermostat to control the fan, contact the equip- ment manufacturer or a qualified heating and air conditioning service person. If your system controls fan
operation (as with most fossil fuel systems), set this item to OFF. Note that with heat pump systems, the fan always cycles with the compressor.
SET CYCLE HEAT, COOL, AUX (ANTICIPATION).
(Installer table steps 4 through 6; step 6 is for heat pump only). These items allow the cycle times in heating, cooling and auxiliary (heat pump systems only) to be increased or decreased. The factory set values can be adjusted higher for longer cycles or lower for shorter cycles.
NOTE: Some manufacturers still instruct you to set the anticipator to the current draw of the equipment. That instruction applies only to mercury bulb or mechanical thermostats; it does not apply to
