Thermostat Operation
The thermostat has a built-in sensor to measure air temperature
at the thermostat. In addition to the built-in sensor, the
thermostat has terminals to connect one auxiliary sensor.
This sensor can either be a room sensor, floor sensor or
an outdoor sensor. If the auxiliary sensor is installed, you must make the
appropriate sensor input setting before the thermostat will
recognize the sensor.
•
• Locate the Sensor setting in the Adjust menu.

Indoor Sensor 076 Outdoor Sensor 070 Indoor Sensor 077 Slab Sensor 079
Room Sensor
A room sensor measures the air temperature in the zone
that the thermostat controls. This measurement is used to
calculate on times for heating operations.
If a built-in sensor reading is not required, the built-in sensor
can be turned off. This removes the built-in sensor from
the temperature average.
Floor Sensor
A floor sensor measures floor temperature in the zone that
the thermostat controls. Floor temperature operates in a
range between the Floor Minimum and Floor Maximum
settings.
•
• Locate the Floor Minimum and the Floor Maximum
settings in the Adjust Menu.
Outdoor Sensor
An outdoor sensor can be connected to the thermostat. The
temperature measured by an outdoor sensor is displayed on
the thermostat. The thermostat communicates the outdoor
temperature to all other devices on the tN4 network.
•
• Locate the Outdoor sensor under the Sensor item in the
Adjust menu.
Mode of Operation Section B
You can operate the thermostat in either the heating or off
modes by manually setting the Mode item to Heat or Off.
The Mode item is found in the Adjust menu. When Mode
is set to Off, the thermostat does not operate except to
provide freeze protection.
•
• Locate the Mode item in the Adjust menu.
