12.3 Analogue thermostat T-165 alarms/problems

RO
An alarm is sent when more than 1 hour have elapsed since the controller received the last radio signal from the thermostat.
The table below lists problems that can occur in standard thermostat T-165.
RU
Indication
The LED on the thermostat flashes
SE
twice
SK
3 4
Indication
No LED indication on the controller when
thermostat setpoint is changed
The actuator never opens
There is 230 V AC power in the wall socket
Repeated radio alarms (LED flashes
rapidly)
The radio connection LED in the controller
continue flashing
Probable cause
Thermostat battery power is running low
The batteries are discharged or wrong type of
batteries is used
The batteries are installed upside down (reverse
polarity)
Transmitter working with reduced signal
intensity
New installations in building shield radio signals
(for example, metal door safe)
The transmitter broken in the thermostat
is
The relative humidity limit is reached
is displayed
Faulty temperature sensor
Faulty temperature sensor
Probable cause
The thermostat battery power is running low
U P O N O R S M AT R I X S PA C E / S PA C E P L U S · I N S TA L L AT I O N A N D O P E R AT I O N M A N U A L
Probable cause
There is no AC power in the controller
Faulty power cable
The controller is installed inside a
metal cabinet, or too close to other
shielding objects
Building structure unfavourable for
radio transmission
The controller is not correctly
installed or positioned
Solutions
Replace the batteries
Replace the batteries
Install the batteries correctly
Force the thermostat to transmit by changing the
temperature setpoint
Replace thermostat
Try to find a new position for the thermostat and/or the
antenna, or, if possible, move the shielding object
Force the thermostat to transmit by changing the
temperature setpoint
Replace the thermostat
Lower the humidity level by increasing ventilation, increasing
the temperature setpoint, or shutting off cooling
Check the connection of the floor sensor
Disconnect the floor temperature sensor and check it with an
ohmmeter. The value must be arount 10 kohms
Contact the installer or replace the thermostat
Solutions
Replace the batteries
Solutions
1. Check that the controller is connected
to AC power
2. Check the wiring
3. Check that there is 230 V AC power in
the wall socket
4. Restart the controller by
disconnecting and reconnecting the
power plug. The controller flashes
red/green at startup
1. Replace the fuse, for the wall socket,
and/or power cable and plug
Change the controller location. If the
problem persists, contact the installer
Check the wiring
