7.14 AUXILIARY HEAT (HEAT PUMP SYSTEMS)
Before auxiliary heat is energized, a 5-minute (factory default) time limit is initiated on a call
for heating. However, this time may be adjusted to 5, 10, 15, or 20 minutes. The time delay
will not apply when the system is switched to emergency heat or when the low BP is activat-
ed. Under these conditions, the auxiliary heat will act as the primary heat source and will
function as first stage heating.
7.15 EMERGENCY HEAT (HEAT PUMP SYSTEMS)
Emergency heat is activated by an on-board selector switch or through a remote switch
wired to terminals EH and SWCOM. When emergency heat is selected, the compressor is
deenergized and all heating calls are acknowledged through the auxiliary heat source (W1).
Cooling calls are ignored when the system is in the emergency heat mode.
7.16 COOLING
Calls for cooling will energize the equipment when the logic panel is set in the cool or auto
changeover mode. If the HVAC system is idle because of a minimum off time or initial power
up, and both heat and cool calls take place, heating will receive the priority providing the
logic panel is set in the auto changeover mode of operation.
7.17 ECONOMIZER
An output terminal controls the economizer power to close it during the unoccupied cycle
(clock input is active). Both power open and power closed options are provided for.
7.18 ADD-ON HEAT PUMP
If the add-on DIP switch is selected, the compressor will be turned off when the panel ener-
gizes auxiliary heat. The NORMAL position will allow auxiliary heat while the compressor is
still running.
