Overheang protecon
Two overheat protecon thermostats are installed in the electrical circular heater EKA. The first one with
automac reset, turns off the heang when the temperature reaches 50 °C and turns on when the temperature
drops below 50 °C. The second with manual reset, turns off the heang when the temperature reaches 100 °C. In
this case need to figure the cause of the overheang of the heater. Eliminate overheang cause, press „RESET“
buon on heaters cover.
Addional overheang thermostat (with automac reset) is installed in the EKA heater with ESKM to protect
the ESKM controller. This thermostat turns off the heang when the temperature reaches 70 °C and turns on when
the temperature drops below 70 °C.

Descripon of operang EKA NV …
Electrical duct heaters EKA NV … are designed with integrated temperature control, one temperature sensor,
setpoint potenometer knob is integrated on the heater lid.
When the heater power supply is switched on, LED 6 on the controller (EKR-K…) PCB (see Fig. 1 on page 4)
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 heang depending on the demand, LED 5 lights (see Fig. 1 on page 4).
Heaters EKA NV … operates by the supply (TJ-K10K) air temperature sensor. Setpoint temperature (0…30) °C.
There can be set the different desired (setpoint) air temperature by potenometer on the top of the heater
casing.
IMPORTANT: If failure appears, power supply must be switched off and only then performed fault
eliminaon works.
Descripon of operang EKA NI …
Electrical duct heaters EKA NI … are designed with integrated temperature control, one temperature sensor,
wired remote control panel (TR5K) for temperature setpoint.
When the heater power supply is switched on, LED 6 on the controller (EKR-K…) PCB (see Fig. 1 on page 4)
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 heang depending on the demand, LED 5 lights (see Fig. 1 on page 4).
Heaters EKA NI … operates by the supply (TJ-K10K) air temperature sensor. Setpoint temperature (0…30) °C.
There can be set the different desired (setpoint) air temperature by wired remote control panel.
If LED 6 lights connuously it means that there is a failure of: supply (TJ-K10K) air temperature sensor or wired
remote control panel TR5K.
IMPORTANT: If failure appears, power supply must be switched off and only then performed fault
eliminaon works.
