Electrical duct heaters EKA NV
…
are designed with integrated temperature control, one
temperature sensor, potentiometer on the top of the heater casing for temperature setpoint.
When the heater power supply is switched on, LED 6 on the controller
(EKR-
KN…)
PCB
(see Fig.
11)
flashes once every 8 seconds if setpoint is 0
°C
and every second if setpoint is
higher than
0
°C.
If
controller turns on the heating depending on the demand, LED 5 lights
(see Fig. 11)
.

air temperature sensor. Setpoint
temperature
(0…30)
°C.
There can be set the different desired
(setpoint)
air temperature by potentiometer on the top
of the heater casing.
If LED 6 lights continuously it means that there is a failure of: supply
(TJ-K10K)
air temperature
sensor or potentiometer on the top of the heater casing.
IMPORTANT:
If failure appears, power supply must be switched off and only then performed
fault elimination works.
