Warmos installation and user guide 4
Electrical connection
If the heater is installed in a bathroom or shower room, it must be protected with a residual current device (RCD) with a
rated residual current not exceeding 30 mA. When installing a heater in a shower room or sauna, consult a qualified
professional electrician.
Install the junction box on the wall behind the heater.
The recommended height of the junction box’s center is
approximately 120mm off the floor. The input tube should be positioned at approximately 100mm off the floor. The wall
brackets have a hole for the power cord. Place the cord in the hole and roll up the possible extra cord. This way the cord is
neatly behind the heater. The electrical wiring diagram contains wiring instructions.
Heaters placed in one room can be parallelly installed. One master heater steers the other heaters. The combined power of
the master and parallel heaters must not exceed 2300 Watts.
If a heater is parallelly mounted, the master heater’s junction
box connector no. 3 is connected to the parallel heater’s connector no. 1.
Walo, Warma ja Wahva heaters can be made into
parallel heaters by turning the control knob into its extreme position, by taking off the knob and then replacing it with the
empty knob cover that is supplied with the junction box. Also a slave unit without its own thermostat is available. It is
connected in the same way.
Electrical wiring:
•
Yellow-green is protective grounding.
•
Blue is working zero N.
•
Brown is heater’s input supply 230V
50Hz to the connector no. 1.
•
Black is the input supply
of the master heater to the parallel heater’s connector 230V no. 3.
•
White is the temperature change/drop from current temperature when 230V is supplied to connector no. 2 (any
line to neutral voltage is suitable (L1, L2 or L3).
•
The protective grounding of the parallel heater is normally connected to the neutral conductor.
•
Black no. 3 of the master thermostat is connected to the brown no. 1 of the parallel heater.
If the building has a Home/Away -switch or similar temperature drop control, it can be connected to connector 2. When
the connector is activated, the temperature will drop from the Home mode to a lower Away mode. The preset value for
temperature drop is 19 °C. The settings can be adjusted in the ecoControl application which is described in more detail
below.
Operation
Switch the power on to position I on the O/I switch. It will take approximately 15 seconds for the thermostat to load itself,
so there is a slight delay in the light turning on. Set the desired temperature on a scale of 5-35 °C.
If the heater’s power is
appropriate for the space, the thermostat will keep the temperature stable.
When the thermostat’s green LED light i
s steadily lit up, the heater is heating. When the heater has reached the set
temperature, the light will turn off. When the light is blinking slowly, it is paired with the ecoControl app or the drop
temperature is on. When the light is blinking fast, the thermostat is waiting for the confirmation of the set values in the
ecoControl app.
