Sequence Of Operation
Comfort System™ is a residential / light commer-
cial zone control system that allows a single
HVAC unit to have up to three separate zones
(nine if three panels are connected together). Each
zone is controlled by its own space thermostat and
motorized zone damper. If any of the zone
thermostats call for heating or cooling, the zones
not calling will have their dampers powered
closed, and the zone(s) calling will have its (their)
damper(s) remain open. The heating or cooling
equipment will also be brought on at the same
time. When all zone thermostats are satisfied, the
heating or cooling equipment turns off and all zone
dampers return to the open position to allow for
continuous air circulation. This is a manual
changeover zone control panel.
Thermostats
The Z-300-HP works with standard, heat pump
thermostats.
All thermostats must be set in the
same mode.
Thermostats must
not
be set in the
auto changeover mode.
Typical System
Verify that all wires have been connected to the
proper terminals and are secure.
Verify that the jumper across the “LL” and “HL”
terminals were removed before connecting the
high and low limit stats.
The low limit (FS-38) should be connected to the
“LL” terminals on the zone control panel. The
high limit (HL-170-HP) should be connected to the
“HL” terminals on the zone control panel.
Zone dampers are powered closed and spring
return open. There will be no power at the panel
damper terminals marked “D” when the damper is
in the open position.
When a green zone LED is on, that zone is calling
for heating or cooling.
To check the system for proper operation, pull the
disconnect for the condensing unit to prevent short
cycling. Next, place all the zone thermostat mode
switches in heat mode and turn down all
thermostat set points. Go to each zone thermostat,
one at a time, and call for heat to verify that the
proper zone dampers are open (and the rest are
closed). Turn the zone thermostat back down
before checking the next zone.
