7. HUMIDITy oUTPUT
This output is used for a humidity demand. This can
be used to humidify or dehumidify.
8. THeRMosTaT InPUT 1 - 4
These terminals are used for power and
communication for thermostat inputs.
Only THM-0300/THM-0500 thermostats are compatible
with this control.
THM-0300 and THM-0500 wiring is Polarity
Sensitive
WIRInG
All signal wiring must be a minimum of 18AWG wire at a maximum of 500ft
3. sysTeM PUMP oUTPUT
This is a dry contact output that can be used for a
system pump. This contact will activate any time a zone
comes on. Pump will not activate in damper zones and
in cooling zones in a mixed system in Geo Mode. When
using zone valves or actuators there is a 60 second
delay to turn on the system pump.
2. Zone 1 - 4 oUTPUT
These are the outputs for the zone device. This can be
a pump, damper or a valve depending on what power
is supplied to terminals 11-12.
1. DeManD oUTPUTs
These are the outputs for the demands. These can be
a Heating and Cooling demand, 24VAC contact, dry
contact TT/Low Temperature demand for a boiler, or
DHW/High Temperature demand.
4. InPUT PoWeR
This input is to power the ZON-0550. 0.5 Amps at 120
VAC is required to power this device.
5. Zone PoWeR
This input is used to power the zone outputs and is
rated for 240VAC, 120VAC or 24VAC.
6. fanCoIl oUTPUT
These are the outputs for the Fancoil demands. These
can be a Fan Demand or an HRV Demand.
