3. INSTALLATION AND ELECTRICAL CONNECTION
The following section is relevant to the push button model (QZC-C) and
PIR model (QZC-D).
The unit should be positioned with the cable glands facing down and securely
xed via the four mounting holes (see Figure 1).
THE UNIT MUST BE SITED AWAY FROM DIRECT RADIATION
FROM THE HEATER AND IDEALLY OUT OF DIRECT SUNLIGHT.
Remove cover using four screws.
Connect supply as to terminals, noting the supply is the incoming supply is to the
left and the load (heater) is connected to the right.
Screw down gable glands and verify cables are securely clamped.
A MEANS FOR DISCONNECTING THE UNIT MUST BE
INCORPORATED INTO THE FIXED WIRING.
THE UNIT IS CAPABLE OF SWITCHING UP TO 6KW. SUITABLE
CABLE MUST BE USED DEPENDENT ON THE INSTALLATION.
THE CABLE GLANDS SUPPLIED (M20) MAY NOT BE SUITABLE
FOR VERY SMALL DIAMETER CABLES. IF NECESSARY THEY
MUST BE REPLACED BY SUITABLE GLANDS WITH
APPROPRIATE IP RATING.
DO NOT EXCEED POWER RATING (MAX 6kW).

4. OPERATION – PUSH BUTTON UNIT QZC-C
To operate the unit, manually press the central red button and release.
Provided the ambient temperature is BELOW the unit’s threshold temperature
the unit will perform a soft start, increasing the gradually power over a timescale
of 2-3 seconds.
The unit will then stay on for a number of minutes before switching off.
To protect against excessive operation that could damage the unit, only two on/off
cycles are permitted per minute.
5. OPERATION – PIR UNIT QZC-D
If motion is detected and the ambient temperature is BELOW the unit’s
threshold set point the unit will perform a soft start, increasing the power
gradually over a timescale of 2-3 seconds.
It will then stay on for a number of minutes before switching off.
If motion is detected whilst the unit is already operating the timer will be reset.
An externally visible red LED indicates when motion is detected.
6. PARAMETER ADJUSTMENT
Both models include two parameter adjustments
- Run Time
- Threshold temperature
MAINS POWER MUST BE DISCONNECTED FROM THE UNIT
BEFORE ATTEMPTING ADJUSTMENT.
To adjust, rst open cover.
On the right hand side of the PCB are two small potentiometers that can be
adjusted with a small at bladed screwdriver (see Figure 2).
The top potentiometer controls the run time in minutes.
The lower potentiometer controls the threshold temperature in degrees C.
The unit will not operate if the ambient temperature is above the threshold
temperature. To effectively disable the temperature control set it to the highest
setting.
