ELECTRICAL CIRCULAR DUCT HEATERS
EKA

IMPORTANT:
If failure appears, power supply must be switched off and only then performed
fault elimination works.
Electrical duct heaters EKA NI … 2NTC are designed with
integrated temperature control, two
temperature sensors, wired remote control panel
(TR5K NTC10)
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
higher than
0
°C.
If
controller turns on the heating depending on the demand, LED 5 lights
(see Fig. 11)
.
Heaters
EKA NI … 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 remote control panel TR5K NTC10.
There can be set the different desired
(setpoint)
air temperature by wired remote control panel
TR5K NTC10.
If LED 6 lights continuously it means that there is a failure of: supply
(TJ-K10K)
or room
(NTC10)
air temperature sensor, wired remote control panel TR5K NTC10.
IMPORTANT:
If failure appears, power supply must be switched off and only then performed
fault elimination works.
Electrical duct heaters EKA NV … PTC/2NTC are designed with
integrated temperature control,
PTC
(air velocity)
and two temperature sensors, potentiometer on the top of the heater casing for
temperature setpoint.
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, controller turns on the heating depending on the demand, LED 2 lights. If there
is no air velocity, controller don’t turns on the heating till air velocity appears.
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
(see
Fig. 11)
is in position 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
(see Fig. 11)
is in position 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 operating mode there can be set the different desired
(setpoint)
air
temperature by potentiometer on the top of the heater casing.
