Tap water operation
The hot water supply takes precedence over the heating. If the flow switch senses a
request for more than 2 l/min of domestic hot water, any CH requests will be
interrupted. After the fan has switched on (code
3
) and there has been an ignition
(code
4
), the controller will switch to domestic water operation (code
6
). During
domestic hot water operation, the rpm of the fan, and therefore the power of the unit, is
controlled by the controller on the basis of the set tap water temperature.
The control system ensures the tap water temperature is correct. The water
temperature can be set between 40°C and 65°C (see par. 8.1). The set tap water
temperature is displayed on the operation panel. The standard setting is 60°C.
You can press the service button during tap water operation to read the actual tap water
temperature.

Heating up unit
In order to provide a fast supply of domestic hot water, a so-called tap comfort function
has been installed in the unit. This function keeps the heat exchanger at the right
temperature (this temperature can be set, see par. 8.2). The tap comfort function has
the following settings:
•
On: ( LED on) The tap comfort function of the unit is continuously switched on.
The unit always immediately provides warm water.
•
Eco: ( LED on) The tap comfort function of the unit is self-learning. The unit will
adjust to the usage pattern of the domestic hot water. This means the heat
exchanger will not be kept warm during the night or during longer absences.
•
Off: (Both LEDs off) The heat exchanger is not kept warm which means the supply of
domestic hot water takes a bit of time. If there is no need for fast delivery of domestic
hot water, the tap comfort function can be switched off.
3.4 PC Interface
The boiler controller is provided with an interface for a PC. A PC can be connected by
means of a special dongle, and the associated software. This facility enables you to
follow the behavior of the boiler controller, the unit and the heat installation over a long
period.
3.5 Test programs
There is an option in the boiler controller, to bring the unit into a test status.
Activating a test program, will switch on the unit with a set fan rotations per minute,
without the control functions intervening. The safety functions do remain active.
The test program is ended by pressing and simultaneously.
