Troubleshooting
This section covers general issues and alarms that can occur with the Smatrix Pulse system, along with the cause and
solutions. A common cause of a problem may be due to improperly installed loops or mixed up or incorrectly installed
thermostats.
Alarms
Issue Cause Resolution
Reoccurring alarms The antenna is installed inside a metal cabinet or
too close to other shielding objects.
• Change the Antenna location.
• If the problem persists, contact the installer.
The Communication Module is installed inside a
metal cabinet or too close to other shielding objects.
• Change the Communication Module location.
• If the problem persists, contact the installer.
Building structure is unfavorable for radio
transmission.
• Change the Antenna location.
• If the problem persists, contact the installer.
Radio transmission error
icon is displayed in the
alarm list
The transmitter is working with reduced signal
intensity.
• Force the thermostat to transmit by changing
the temperature setpoint.
• Replace the thermostat.
The Antenna is installed inside a metal cabinet or
too close to other shielding objects.
• Change the Antenna location.
• If the problem persists, contact the installer.
The Communication Module is installed inside a
metal cabinet or too close to other shielding objects.
• Change the Communication Module location.
• If the problem persists, contact the installer.
New installations in the building are shielding 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 in the thermostat is faulty. • Force the thermostat to transmit by changing
the temperature setpoint.
• Replace the thermostat.
Relative humidity icon is
displayed in the alarm list
The relative humidity limit is reached. • Lower the humidity level by increasing the
ventilation or activating a dehumidifier.
Floor temperature sensor
icon is displayed in the
alarm list
Incorrect thermostat control mode or temperature
sensor not connected.
• Select the correct thermostat control mode in
settings Menu 04.
There is a faulty temperature sensor. • Check the connection of the floor sensor.
• Disconnect the temperature sensor and check
it with an ohmmeter. Make sure the value
aligns with the temperature sensor diagram.
Outdoor temperature
sensor icon is displayed in
the alarm list
Incorrect thermostat control mode or temperature
sensor not connected.
• Select the correct thermostat control mode in
settings Menu 04.
There is a faulty temperature sensor. • Check the connection of the outdoor sensor.
• Disconnect the temperature sensor and check
it with an ohmmeter. Make sure the value
aligns with the temperature sensor diagram.
Indoor temperature sensor
icon is displayed in the
alarm list
There is a faulty temperature sensor. • Contact the installer or replace the
thermostat.
Remote temperature
sensor icon is displayed in
the alarm list
Incorrect thermostat control mode or temperature
sensor not connected.
• Select the correct thermostat control mode in
settings Menu 04.
There is a faulty temperature sensor. • Check the connection of the remote sensor.
• Disconnect the temperature sensor and check
it with an ohmmeter. Make sure the value
aligns with the temperature sensor diagram.
