IMPORTANT: If failure appears, power supply must be switched off and only then performed fault
eliminaon works.
Descripon of operang EKA NV … PTC/2NTC*
Electrical duct heaters EKA NV … PTC/2NTC are designed with integrated temperature control, PTC (air
velocity) and two temperature sensors, potenometer on the top of the heater casing for temperature setpoint.
When the heater power supply is switched on, controller (EKR-K) is in preparaon mode for 30 seconds, LED 1
flashes once every 5 seconds. If air velocity is detected by PTC sensor (rapid LED 1 flashes when Min. 1,5 m/s is
detected) aer preparaon mode ends, LED 1 will start to flash once every second and controller will iniate the
heang based on demand, LED 2 is indicang when heang is iniated. If there is no air velocity detected, controller
will not iniate the heang unl air velocity detected.
Heaters EKA NV … PTC/2NTC can operate in two modes:
1. Control by the supply air temperature sensor (TJ-K10K), when the first (1) switch of JP1 -(R37) (see Fig. 1 on
page 4) is in posion OFF. LED 1 flashes once per second. Setpoint temperature (0…30) °C.
2. Control by the supply (TJ-K10K) and by the room (NTC10) air temperature sensor, when the first (1) switch of
JP1 -(R37) (see Fig. 1 on page 4) is in posion ON. LED 1 flashes twice per second. Setpoint temperature (15…30) °C.
In this mode is preprogrammed the minimum (15°C) and the maximum (40°C) temperatures of supply air. The room
air temperature sensor is mounted in the wired panel TR NTC10.
Depending on the operang mode there can be set the different desired (setpoint) air temperature by
potenometer on the top of the heater casing.

2. Control by the supply (TJ-K10K) and by the room (NTC10) air temperature sensor, when the first (1) switch of
JP1 -(R37) (see Fig. 1 on page 4) is in posion OFF. LED 6 flashes once per second. Setpoint temperature (15…30) °C.
In this mode is preprogrammed the minimum (15°C) and the maximum (45°C) temperatures of supply air. The room
air temperature sensor is mounted in the wired remote control panel TR5K NTC10.
Depending on the operang mode there can be set the different desired (setpoint) air temperature by wired
remote control panel TR5K NTC10.

Electrical duct heaters EKA NI … PTC/2NTC are designed with integrated temperature control, PTC (air velocity)
and two temperature sensors, wired remote control panel (TR5K NTC10) for temperature setpoint.
When the heater power supply is switched on, controller (EKR-K…) is in preparaon mode for 30 seconds, LED
1 flashes once every 5 seconds. If air velocity is detected by PTC sensor (rapid LED 1 flashes when Min. 1,5 m/s is
detected) aer preparaon mode ends, LED 1 will start to flash once every second and controller will iniate the
