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.
