7.1 Temperature Control
The hot water flow temperatures have been factory preset. If you wish to change the
temperatures then you need to access the electronic box and take off the plug
covering the potentiometers – P1 [hot water flow temperature] [see appendix 2].
Twisting P1 potentiometer clockwise with a screwdriver will increase the temperature
and anti-clockwise will reduce the temperature.
7.2 Heat Meter
If provided the booklet is attached to these instructions.
7.3 Cold Water Meter
If provided the booklet is attached to these instructions.
7.4 System Safety Relief Valve
It is assumed that there are system safety valves in place to take care of this so no
pressure relief is provided within the unit, although please note that maximum
pressure is 6 bar.
7.5 Pre-Heat Function
There is a pre-heat function available which should only be used if length of time to
get hot water from the unit takes too long as this function might aid quicker provision
of the hot water. If this function is required, then obtain access to the electronic box
and locate the dip switches [see Appendix 2]. To turn on the pre-heat function then
flick dip switch 5 to on [see Appendix 3]. This will then heat the exchanger when it
goes to 15°C below hot water set temperature and switches back off when it reaches
10°C below hot water set temperature. This could in turn speed up time to achieve
hot water set temperature.
8.0 FAULT FINDING
Check the fault light on the electronic box [see Appendix 3].
If there are no fault lights, then firstly switch off power to the unit, wait for 10 seconds
and then re-start the unit as this will reset the stepper motors.
If the unit still does not operate, then the next step is to check all wiring is correctly
connected to the right component, especially if connectors have been taken off at
any stage. Refer to Appendix 2 for wiring explanation.
If the above does not rectify the problem and the unit still does not operate
satisfactorily, then below are some suggestions of potential issues. Alternatively
consult supplier for assistance.
