Description Of Operating Cva Mpi; Description Of Operating Cva Mpe - Cairox CVA M Series User Instruction

Control by the supply (TJ-K10K) and by the room (NTC10) air temperature sensor, when the first (1) switch of
2.
JP1 -(R37) (see Fig. 1 on page 4) is in position 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 operating 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
elimination works.

DESCRIPTION OF OPERATING CVA MPI ... PTC/2NTC*
Electrical duct heaters CVA MPI ... 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-K) is in preparation 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) after preparation mode ends, LED 1 will start to flash once every second and controller will initiate the
heating based on demand, LED 2 is indicating when heating is initiated. If there is no air velocity detected, controller
will not initiate the heating until air velocity detected.
Heaters CVA MPI ... PTC/2NTC can operate in two modes:
Control by the supply air temperature sensor (TJ-K10K), when the first (1) switch of JP1 -(R37) (see Fig. 1 on
1.
page 4) is in position OFF. LED 1 flashes once per second. Setpoint temperature (0...30) °C.
Control by the supply (TJ-K10K) and by the room (NTC10) air temperature sensor, when the first (1) switch of
2.
JP1 -(R37) (see Fig. 1 on page 4) 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.
IMPORTANT: If failure appears, power supply must be switched off and only then performed fault
elimination works.
