Dip Switch Settings (continued)
HEAT PUMP or HEAT/COOL: Sets the control for the
heating and cooling system equipment. If a heat pump
is to be used, set the switch to the ON position. When
different equipment is used for heating and cooling
(i.e. furnace and air conditioner), set the switch to the
OFF position.
ELECTRIC/ GAS: If electric heat is to be used, set the
switch to the ON position. This will turn on the fan (G
output terminal) with a heat call (W1 output terminal). If
the switch is left in the OFF position, it is assumed that
the heating equipment will control the fan operation. For
Dual Fuel Heat Pump systems, leave this switch in the
GAS position.
NO PURGE / PURGE: If the NO PURGE/PURGE switch
is set to PURGE, the G terminal will remain energized
for a one minute purge delay following the completion of
a compressor call. If the NO PURGE/PURGE switch is
set to NO PURGE, the G terminal will de-energize
immediately following the completion of a compressor
call. The NO PURGE setting is designed for use with
systems where the furnace or air handler has a built in
fan purge. The following chart details the zone panel fan
output and damper hold times when a heating or
cooling call is satisfied:

ZONE/VAC (VACATION) SELECTOR: This switch
allows the homeowner to switch from normal operation
(ZONE) to a VACATION mode. In VACATION mode
(switch in the ON position), Zone 1 becomes the only
zone from which a call for heating or cooling is
recognized. Additionally, when in Vacation mode,
damper outputs do not change – they remain in the
open position. The Vacation LED will illuminate when
the switch is in the VACATION position.
E-HEAT SELECTOR: This feature can only be used
with heat pump systems. When the EMERGENCY
HEAT switch is in the ON position, any call for heat will
be answered with auxiliary heat equipment outputs (W1
and W2). This feature enables the homeowner to
activate the Emergency Heat mode when heat/cool
thermostats are installed in all zones.
LEDs
POWER – Blinks during normal operation. Starts to
blink appoximately 6 seconds after power up.
HEAT – Lights when equipment heating outputs are
energized (LEDs next to equipment terminals show
which outputs are on). This output will flash if the
heating high temperature limit has been reached. If this
LED is flashing while the cooling LED is on or flashing,
then this indicates an open or short circuit in the DAS.
COOL – Lights when equipment cooling outputs are
energized (LEDs next to equipment terminals show
which outputs are on). This output will flash if the
cooling low temperature limit has been reached. If this
LED is flashing while the heating LED is on or flashing,
then this indicates an open or short circuit in the DAS.
FAN ON – Lights when equipment G terminal
is energized.
VAC – Lights when ZONE/VAC switch is in
VAC position.
E-HEAT – Lights when E-HEAT switch is ON.
ZONE 1 to ZONE 4 – Lights when the Normally Open
(NO) damper terminal for that zone is energized
(i.e. LEDs show which zones are NOT calling when the
HVAC equipment is operating).
1
The G terminal will remain energized for 1 minute.
