ELECTRICAL CIRCULAR DUCT HEATERS
Heaters EKA NI ... PTC ... (PH) 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 1 lights continuously it means that there is a failure of: PTC (air velocity) sensor, supply
(TJ-K10K) air temperature sensor, wired remote control panel TR5K.
When the heater power supply is switched on, after power supply interruption or after any
failure, controller in preparing mode for 30 seconds.
IMPORTANT:
If failure appears, power supply must be switched off and only then performed
fault elimination works.
Description of operating EKA NIS ... PTC ... (PH)
Electrical duct heaters EKA NIS ... PTC ... (PH) are designed for the heaters power (0...100) %
2
control by analog signal input (0...10) VDC and with integrated PTC (air velocity) sensor.
When the heater power supply is switched on, controller (EKR-KN...) is in preparing mode for 30
seconds, LED 1 flashes once every 5 seconds. If there is air velocity (Min. 1,5 m/s) in the duct heater
after preparing mode, LED 1 flashes once per second and controller turns on the heating depending
on analog signal, LED 2 lights. If there is no air velocity, controller don't turns on the heating till air
velocity appears.
If LED 1 lights continuously it means that there is a failure of PTC (air velocity) sensor.
When the heater power supply is switched on, after power supply interruption or after any
failure, controller is in preparing mode for 30 seconds.
IMPORTANT:
If failure appears, power supply must be switched off and only then performed
fault elimination works.
Description of operating EKA NV ... 2NTC
Electrical duct heaters EKA NV ... 2NTC are designed with integrated temperature control, two
2
temperature sensors, potentiometer on the top of the heater casing for temperature setpoint.
When the heater power supply is switched on, LED 6 on the controller (EKR-KN...) PCB (see Fig.
11) flashes once every 8 seconds if setpoint is 0 °C and every second if setpoint is
controller turns on the heating depending on the demand, LED 5 lights (see Fig. 11).
Heaters EKA NV ... 2NTC operates by the supply (TJ-K10K) and by the room (NTC10) air
temperature sensor. 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 panel TR NTC10.
There can be set the different desired (setpoint) air temperature by potentiometer on the top
of the heater casing.
If LED 6 lights continuously it means that there is a failure of: supply (TJ-K10K) or room (NTC10)
air temperature sensor, potentiometer on the top of the heater casing.
