Descrip on of opera ng EKA NIS ... (PTC...PS) *
Electrical duct heaters EKA NIS ... (PTC...PS) are designed for the heaters power (0...100) % control by analog
signal input (0...10) VDC, with integrated PTC (air velocity) and PS (air pressure) sensors.
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) and air pressure is greater than min 20kPA 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 and or there is not enough pressure in the duct, controller will not ini ate the
hea ng un l air velocity and or pressure is detected.
Pre-heater casing and air duct before pre-heater should be insulated with rock wool 10cm (R~2,4m²K/W).
Depending on the moun ng posi on of the heater in the duct rela ve to the motor (pre- or post-motor), the
pressure hose must be placed on the "-" or "+" pipe, respec vely.
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 ... 2NTC*
Electrical duct heaters EKA NV ... 2NTC are designed with integrated temperature control, two temperature
sensors, poten ometer on the top of the heater casing 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 depending on the opera ng mode. If controller turns on the hea ng depending on the demand, LED 5 lights
(see Fig. 1 on page 4).
Heaters EKA NI ... 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 ON. LED 6 flashes twice per second. Set point 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 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.
IMPORTANT: If failure appears, power supply must be switched off and only then performed fault
elimina on works.
