• Panel controls four zones.
• Zone4 damper can be used as a fresh air
damper. A timer on panel sets the minutes
of fresh air per hour.
• Capable of two-stage heating and two-
stage cooling for gas/electric systems and
three-stage heating and two-stage cooling
for heat pump systems.
• Compatible with gas/electric, oil, electric
and hydronic systems and both conventional
and dual fuel heat pumps. An optional
supply air temperature sensor can be used
to limit supply air temperature and prevent
over-heating and freeze-up. Maximum and
minimum supply air temperatures can be
set on the panel.
• Optional outdoor air temperature sensor
can be used to limit multi stage heating in
moderate weather.
• Optional outdoor air temperature sensor
used with dual fuel heat pumps to control
switch-over to fossil fuel heating without
the use of external thermostats or relays.
• Compatible with low cost, heat-cool
thermostats.
• Compatible with automatic change-over
thermostats allowing any zone to call for
heating or cooling.
• Second and third stage startup controlled
by a timer located on the panel.
• A heat pump thermostat can be used in
Zone1 for emergency heat control.
• An optional purge cycle at the end of
heating or cooling call.
• Limit use of multi stage heating and cooling
when less than half the zones are calling.
• One-Zone operation eliminates resetting all thermostats when going on vacation. All dampers and HVAC system are
controlled by the Zone1 thermostat.
• Compatible with most 24VAC powered and battery powered thermostats.
• Compatible with all 24VAC damper actuators including spring return and power open/power close types.
