than the temperature set
on the thermostat
Incorrect minimum/maximum limitation • Change the minimum/maximum limitation in
the Smatrix Pulse App.
The display for the Digital
Thermostat (T-169) is not
showing any information
The battery is discharged, or the wrong type of
battery is used.
• Replace the battery (CR 2023V).
The battery is installed incorrectly (reverse polarity). • Install the battery correctly.

The thermostat battery power is running low. • Replace the battery.
Low radio signal detected
(sporadic communication
with the connected unit)
The thermostat is out of range. • Force the thermostat to transmit by changing

New installations in building shield radio signals (for
example, a metal door safe).
• Try to find a new position for the thermostat
and/or the Antenna, or, if possible, move the
shielding object
The transmitter is working with reduced signal

sensor
An error has been detected with the external sensor
connected to the thermostat.
• Make sure the correct thermostat control
mode in settings Menu 04 is set in the Digital
Thermostat (T-169).
• Check the connection of the external sensor.
• Disconnect the external sensor and check it
with an ohmmeter. Make sure the value aligns
with the temperature sensor diagram.
• If the error persists, replace the external
sensor.
Faulty relative humidity
sensor
An error has been detected with the internal relative
humidity sensor in the thermostat.
• Replace the thermostat.
Relative humidity sensor
limit
The relative humidity limit is reached. • Lower the humidity level by starting a
dehumidifier or increasing the supply
temperature setpoint.
