Heating Operation - Vaillant 24 E Instructions For Use Manual

Obtaining hot water
On opening a hot water tap (3) at a supply point (basin,
shower, bath, etc.) the boiler will automatically operate
to deliver hot water.
On closing the tap the boiler switches OFF (or continues
to operate for central heating if required). The pump and
fan will continue to operate for a short period.

Setting the external controls
• Set the room thermostat (3) and/or the thermostatic
radiator valves (4) according to the instructions
supplied with the control(s).
Hint!
Vaillant offer room thermostat/time control
accessories which give accurate and economic
room temperature control as well as improved
comfort. Ask your installer!
Fig. B.8: Setting the external controller
The boiler will now operate automatically to provide
central heating for the conditions selected on the
external controls (turboMAX pro will also provide dome-
stic hot water on demand). After the boiler stops opera-
ting the pump and fan will continue to operate for a
short period to fully disperse the heat from the boiler.
Note:
The boiler incorporates an anticycling
economiser control to prevent energy wasteful
ON and OFF operation of the boiler for short
periods when in the central heating mode. When
turning the room thermostat to a higher setting
there may therefore be a short delay before the
boiler operates.
