Figure 6: Resetting the temperature cut-out
1. Temperature cut-out sauna heater
2. Glass fuse 1 Ampere
Symptom Possible cause Remedy
Heater element
in heater stone
compartment does
not warm up.
1. Temperature settings on control panel do not cor-
respond to operating status?
2. Some of the heater fuses on the main switchbo-
ard can have tripped out?
3. Resistor coil in the heater element faulty?
4. Internal heater PCB fault?
1. Set temperature to correspond to heater element
operation in stone compartment.
2. Check and replace/reset the fuses in the main
switchboard.
3. An authorised electrician is required to find the
fault.
4. An authorised electrician is required to find the
fault.
Lights in the sauna
do not come on
when switched on
at the control panel.
1. Internal glass fuse in heater faulty?
2. Is lighting connected via the heater?
3. Internal heater PCB fault?
1. Switch offat main power switch on heater and
replace glass fuse. See fig 6.
2. Verify with authorised electrician who performed
installation of heater/lighting.
3. An authorised electrician is required to find the
fault.
Heater does not
work, control panel
does not light up.
1. The main power switch is off?
2. Or all heater fuses on the main switchboard can
have tripped out?
3. Loose contact in cabling between heater and
control panel?
4. The specific 12VDC output on one of the PCB's
RS485 modular jack to the control panel is faulty
due to short-circuit?
5. Transformer on PCB in heater faulty?
6. Control panel faulty?
7. Internal temperature cut-out triggered? For
more information, see the Temperature cut-out
section.
1. Turn heater main power switch.
2. Check and replace/reset the fuses in the main
switchboard.
3. Switch offheater main power switch and connect
each/paired cable to the control panel. Switch on
heater main power switch again. If this does not
help, an authorised electrician is required to find
the fault.
4. Requires an authorised electrician to find the
fault, faulty 12VDC output is indicated by LED out
next to the RS485 output. NB: if the fault is in the
RJ10 cable to the control panel, do not click into
a working vacant RS485 outlet to avoid causing a
fault in that outlet. RJ10 cable must be replaced/
contacts fitted in the event of a fault.
5. An authorised electrician is required to find the
fault.
6. An authorised electrician is required to find the
fault.
7. Reset the heater temperature cut-out.
The heater fuses/
ground fault inter-
rupt device on the
main switchboard
trip as soon as the
heater is turned on.
1. There is a short-circuit at the heater GND. Can
be due to a faulty heater element?
2. Lighting connected to and controlled via the
heater faulty?
3. The heater has not been used for a long period,
causing an insulation fault in the heater ele-
ment?
4. Heater has had too much water poured on it?
5. Other internal heater fault?
1,2,3,4,5. Do not use the heater, switch offat main
heater main switchboard trip and disconnect hea-
ter fuses on the main switchboard. An authorised
electrician is required to find the fault.
Table 1: Troubleshooting the sauna heater
NOTE! When the temperature cut-out (in the hea-
ter) is triggered due to excessively high operating
temperature it can only be reset once the cut-out
temperature has decreased approximately 20°C. If
the temperature cut-out instead is triggered due to
the operating temperature being too low (ambient
temperature below -10°C), the cut-out temperature
must be increased before it can be reset.
