(prepared by Saunafin)
Control & Elite sensor cable can also
be connected to any of 6, 7, 8, 9

Temperature Sensor Location
Sensor location is very specific and very important for proper function of the sauna heater.
Sensor must be 3” to the front or open side of heater (not in corner), 1” down from ceiling.
Humidity + Temperature Sensor Installation (Combi Elite Only)
SAUNA VENTILATION
Sensor cable wires are very small.Ensure connection is tight and secure
Indoor Sauna: Position the air inlet and outlet vents as far away from one another as possible (diagonally opposite).
Air inlet vent should be low, behind (or close to heater). The outlet vent should be located high on a wall (A), and should
be about 19” sq. It should be directed back into house – it should not be discharged directly to the outside. If outlet wall
is inaccessible, install outlet vent in far corner of ceiling & duct over drop ceiling to area in front of sauna (B).
Outdoor Saunas: Outdoor saunas generally have easy access. Some choose to hold off on vents initially and add later if
it appears to be necessary.)
Do not install inlet and outlet vents on same wall. Bad ventilation can be worse than no ventilation.

MAINTENANCE
To prevent build up of lime-scale and higher salt/mineral levels empty the reservoir after each use. If this is not done, foam
build up may occur which can “trick” water level probe to detect higher than actual water level and risk burning out steam
element.
Annually
Combi water reservoir should be descaled at least once a year using “Tylo De-Scaler” (see full manual).
Clean water level probe using a cloth (see full manual).
Check stone compartment. Remove all stones. Remove all small stones, gravel and lime-scale from rock compartment.
Replace damaged stones with new ones as required.
First Use:
Turn onheater for one hour to “burn off” any new
paint or element oils. The water reservoir does not
need to be operating.
There may be a little smoke initially. This is normal.
Very Important:
Clean rocks before use to remove
dust.
Sauna rocks may only be placed in
center (deep) rock compartment (1).
Never place stones on top of the side
air chambers (2). This will obstruct air
circulation, causing the unit to
overheat and the cut-out switch to
activate.
Cut-out for heater is on left side.
When tripped, stem ispushed out.
(When tripped, control goes blank.

Error codes
Should an error occur in a device or associated equipment (control panel, temperature sensor, etc.)
an error message will be displayed (see Error list).
e following error codes are used:
No. Error Comments/Troubleshooting
1 Temperature sensor in the
room not connected or faulty.
Is the sensor at the input intact/interrupted? Is it indica-
ting an incorrect value or loose?
2 Temperature sensor in steam
tank not connected or faulty.
Is the sensor at the entrance intact/interrupted? Is it
indicating an incorrect value or loose? e sensor value
is displayed under the water temperature status under
Congure. On operation is not interrupted if an error
occurs. Standby operation not permitted.
3 e relay board has overheated. Wait until the temperature drops to 20 °C; it should be
possible to start it aer that. If the temperature remains
too high the error will recur.
4 e level electrodes in the ste-
am tank are short-circuited.
Check that the electrode pins are touching the electrode
tube or alternatively the cables. Clean the water tank and
level pins.
5 e steam tank overfull level
electrodes are not working.
e top electrode (high) has not detected the water
level within the maximum lling time, or the maximum
lling time for the water tank in Congure is too short
due to low ow. Default value is 6 minutes. Is the inco-
ming water switched on? Is there a loose contact in the
electrode wire connection? Coating on electrode pins
(level electrodes)? Check the value in Congure/Status at
start-up to ensure that the level has changed from low to
mid/high during lling. If the level has not changed then
both level pins (mid/high) are faulty. If the level has only
changed from low to mid, the high pin is faulty.
6 Contact lost with the control
panel..
Are the control panel's RJ10 connections loose? Poor
connection?
7 Contact lost with temperature/
humidity sensor.
Are the temperature/humidity sensor's RJ10 connections
loose? Poor connection?
8 e steam tank has overheated. Temperature in water tank is too high. Check the steam
pipe along its length, and its dimensions. Check whether
NTC in the tank is intact and showing the correct value:
at room temperature/25 °C, this is about: 10 kilo ohm.
9 Real-time clock (RTC) commu-
nication error.
Has the system lost power for a long period? Set the time
and date.

Error codes (continued)
No. Error Comments/Troubleshooting
10 Contact with the add-on board
has been lost.
Check the RJ45 cable between the circuit board and the
add-on board. Is the green LED lit on the add-on board?
Try to start ON operation again to try and restore the
contact. Try replacing the RJ45 cable or add-on board.
12 Steam tank level electrodes are
not working, mid failure.
Check the cable connections between the circuit board
and the mid electrode. Check if the mid electrode pin is
coated with surface coating; if so, clean the electrode pin.
13 Humidity sensor is not wor-
king.
Try restarting the system or replacing the temperature/
humidity sensor that is connected to the RS485 input.
14 Temperature sensor not wor-
king.
Try restarting the system or replacing the temperature/
humidity sensor that is connected to the RS485 input.
15 Contact lost with the relay
board.
Appears when the primary unit has lost contact with
the connected secondary unit. e system will x itself.
Check synchronisation cables and voltage to secondary
units. Aer the error is rectied, the system reboots to
include all secondary units in system operation.
16 Temperature cut-out activated
and must be reset manually.
Combined temperature cut-out/temperature sensor in
sauna is reset via a push button on the sensor.
17 Too many temperature/humidi-
ty sensors connected
Only one temperature and humidity sensor may be con-
nected to the system's RS485 bus.

Symptom Possible cause Remedy
Heater is on but does
not create steam. 1. Water level incorrect. Below minimum water
level for safety sensor?
2. Humidity settings not programmed as intended
3. Water reservoir temperature cut-out activated?
4. Heater element in reservoir faulty?
5. If the sauna structure has defi cient ventilation in
conjunction with dry sauna and high sauna tem-
perature (operating with no water in reservoir), the
temperature cut-out can activate because of higher
radiating temperature in the heater.
1. Fill up reservoir.
2. Confirm control setting-review control manual.
3. Reset temperature cut-out. For more information,
see the section on temperature cut-out on fi gure 9
page 15 in full manual. If the steam function does not
