OUTDOOR TEMPERATURE SENSOR (INCLUDED) Outdoor temperature can be measured by attaching the included 8052 sensor to the T1 and T2 terminals. The outdoor sensor must be enabled in the installer setup menu. Heat pump models can use the outdoor temperature to effectively utilize the heat pump: • When the outdoor temperature is lower than the Low Balance Point, the heat pump will be locked out and only auxiliary heating will be used to provide heating.
REMOTE TEMPERATURE SENSOR (OPTIONAL) A remote temperature sensor can be used for control if the thermostat is to be mounted in a concealed location or a remote sensor can be averaged with the thermostat sensor to control a large space. An 8051 flush mount or 8053 surface mount remote temperature sensor can be attached to the T1 and T2 terminals and mounted in a recommended area.
WIRELESS SENSORS This thermostat is compatible with the following AprilAire wireless sensors: • Model Z10IDT Indoor Temperature and Humidity Sensor Up to eight of these sensors can be connected to the thermostat. Connected sensors will automatically be averaged, or individual sensors can be selected for scheduled events. • Model Z10ODT Outdoor Temperature and Humidity Sensor One sensor can be connected to the thermostat. The wireless sensor settings can be found under the thermostats’ installer settings.
POWER AND RESET OPTIONS The thermostat is powered from 24VAC. In the case of power loss, the thermostat will maintain the clock for 2 hours. The thermostat has a memory backup that saves the thermostat settings in case of power interruption. The thermostat can be set back to factory defaults from the installer settings menu. See Installer System Settings section for details. The factory reset does not clear thermostat account information from the AprilAire Wi-Fi Thermostat App.

INDOOR AIR QUALITY SYSTEM SETTINGS TABLES TABLE 2 – HUMIDIFIER SYSTEM SETTINGS The following tables contain the Indoor Air Quality system settings and their details. Default settings are shown in bold. The availability of some settings is dependent upon the value of other settings. The use of outdoor temperature data enables additional Indoor Air quality functionality.
TABLE 2 – HUMIDIFIER SYSTEM SETTINGS TABLE 2 – HUMIDIFIER SYSTEM SETTINGS Factory default setting (bold) and setting range System setting Description Allowed Humidifier Operation Selects when humidification is allowed to occur relative to heating and fan operation. NOTE: Without Fan is only available when Humidifier Installed is set to Yes/Standalone. It allows humidification to occur without activating an HVAC fan and should only be used when the humidifier is mounted independently of any HVAC system.
