Thermostats
The external temperature sensor input can be used
to connect a floor temperature sensor on the Digital
Thermostat (T-169) (part number A3800169) and Mini
Sensor (T-161) (part number A3800161). This sensor can
be used to maintain minimum floor temperatures and
protect wood flooring. Minimum and maximum values
can be set or modified through the Smatrix Pulse App or
on the Digital Thermostat if no Communication Module is
installed in the system.
Wiring the Floor Sensor (optional)
Caution!
If more than one hour has passed between
startup of the thermostat, and the sensor
wires are connected, remove the battery from
the thermostat, wait 30 seconds, and reinsert
the battery again. The thermostat will now be
configured with a floor sensor.
• Remove the breakout plastic on the back of the
thermostat.
• Press the push buttons on the connection terminals.
• While pressing the push buttons, insert the two wires from
the sensor cable (non-polarized) into the connection
terminal.
Powering Up the Thermostats
Remove the plastic transportation strip from the battery to
start the thermostat.
The thermostat uses a single CR2032 3V button cell lithium
battery which provides about two (2) years of battery life if
it is positioned within radio range of the controller. Ensure
that the battery is correctly inserted in the thermostat.
The A3800169 Digital Thermostat (T-169) will perform a
self-test for 10 seconds when the transportation strip or
the battery has been inserted. Allow the thermostat to
complete the self-test prior to linking to a Controller.
The A3800161 Mini Sensor (T-161) will also perform a self-
test for 10 second when the transportation strip or the
battery has been inserted. The LED on the front will flash
during start up. Allow the sensor to complete the self-test
prior to linking to a Controller.
