Descripon of operang EKA NV … (PTC…PS)
Electrical duct heaters EKA NV … (PTC…PS) are designed with integrated temperature control, PTC (air
velocity), PS (air pressure) and temperature sensors, setpoint potenometer knob is integrated on the heater lid.
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. Heaters EKA NV… (PTC…PS) operates by the supply (TJ-K10K)
air temperature sensor.
EKA NV … PTC … setpoint temperature (0…30) °C
EKA NV … PTC/PS setpoint temperature (-10…50) °C
There can be set the different desired (setpoint) air temperature by potenometer on the top of the heater
casing.
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.
Descripon of operang EKA NIS …
Electrical duct heaters EKA NIS … are designed for the heaters power (0…100) % control by analog signal input
(0…10) VDC.
When the heater power supply is switched on, LED 6 on the controller (EKR-K…) PCB (see Fig. 1 on page 4)
flashes every second. If controller turns on the heang depending on analog signal, LED 5 lights (see Fig. 1 on page
4).
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 … (PTC…PS)*
Electrical duct heaters EKA NI … (PTC…PS) are designed with integrated temperature control, PTC (air velocity)
PS (air pressure) and temperature sensors, wired remote control panel (TR5K) 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) 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.
Heaters EKA NI … (PTC…PS) operates by the supply (TJ-K10K) air temperature sensor.
EKA NI … PTC … setpoint temperature (0…30) °C
EKA NI … PTC/PS setpoint temperature (-10…50) °C
There can be set the different desired (setpoint) air temperature by wired remote control panel.
Pre-heater casing and air duct before pre-heater should be insulated with rock wool 10cm (R~2,4m²K/W).
