Equipment Control Module Wiring
Outdoor temperature sensor (included)
Outdoor temperature can be measured by installing an 8052 sensor to the ODT terminals and enabling the outdoor
sensor in the installer set-up menu. When an outdoor sensor is installed, the features below will be enabled.
In heat pump mode the outdoor temperature sensor can be used to efficiently utilize an air source heat pump:
• When the outdoor temperature is less than the Low Balance Point, the heat pump will be locked out and only
auxiliary heating will be used to provide heating.
• When the outdoor temperature is higher than the High Balance Point, the auxiliary heating will be locked out and
only the heat pump will be used to provide heating.
Indoor Air Quality functions can use the outdoor temperature sensor to:
• Control humidification setpoint based on outdoor temperature to prevent condensation
• Lock out humidification for temperatures over 60°F or below -30°F.
• Lock out ventilation based on high and/or low outdoor temperatures.
• Display outdoor temperature on thermostat.
Outdoor temperature sensor should
be mounted:
• On side of building out of direct sunlight
(north side recommended).
• Above snow line.
• At least 3’ away from exhaust vents and
condensing lines.
• Using less than 300’ of wire.
Wire specifications:
C – 24VAC common
18-24 gauge thermostat wire
