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.
