FEATURES
The 8083 Flush Mount Temperature and Humidity Module can be used to remotely sense
temperature and humidity in a space. When wired to any Aprilaire thermostat that features
Support Module capabilities, a combination of up to four total Model 8083 Flush Mount Modules
and Model 8081 TT or Model 8082 TrH Support Modules can be used to remotely monitor the
temperature and humidity in various rooms or throughout a larger space. The temperature and
humidity readings can also be averaged to create controlling values for the thermostat.
INSTALLATION INSTRUCTIONS
1. Select a location for mounting the module.
Locate the module as you would locate a thermostat.
• Mount on an interior wall, in a frequently occupied space.
• Keep the module 18" away from an outside wall.
• DO NOT mount the module:
– Behind doors, in corners or other dead air spaces.
– In direct sunlight or near lamps, appliances, dimmer switches or other sources of heat.
– On an outside wall or wall exposed to an unconditioned space (i.e. garage).
– In the flow path of a supply register, in stairways or near outside doors.
– On a wall where a concealed pipe or ductwork could influence the module.
– Near sources of electrical interference such as light switches.
Maximum wire length from the module to the thermostat is 1000 feet.
2. Remove the metal disk from the front
of the module.
Address Selection – Dip Switch A1 and A2
Each Flush Mount Module and/or Support Module
must have its own unique address. The address
for the Flush Mount Module is set as shown on
the diagram to the right.
Temperature and Humidity Sensor Mode – Dip Switch T and H
The T dip switch setting determines if the temperature sensor is a controlling (on) or monitoring
(off) value. The H dip switch setting determines if the humidity sensor is a controlling (on) or
monitoring (off) value.
If the dip switch is set to off, the thermostat will use the sensor value as a monitoring value which
can be displayed on the thermostat and read over the thermostat’s communication interface.
If the switch is set to on, the thermostat will consider this sensor to be a controlling value. If
multiple temperature or humidity sensors are set to controlling the thermostat will average the
values for control. The averaged value will also be displayed as the controlling temperature or
humidity value on the thermostat.
