Extra heating for the bathroom
Extra heating for the bathroom makes use of the d.h.w. pump overrun. It is used
especially during intermediate seasons by supplying surplus heat to the bathroom, in
addition to normal bathroom heating.
Surplus boiler heat after a d.h.w. heating cycle is supplied to the pump heating circuit
via overrun of heating circuit pump 2. The pump overrun is fixed at 30 minutes.
This function is an uncontrolled fixed process, parallel to the actual operation of the
pump heating circuit.
When automatic summer / winter changeover of the pump heating circuit has
responded, extra heating for the bathroom will also be switched off.
