CONNECTING COLD AND HOT WATER
The settings for hot water are made in the compatible
product's menu system.
Stop temperature for hot water must be at least 60°C.
Install as follows:
• controlling hot water sensor (BT6) (placed in the
middle of the water heater)
• shut-off valve
• non-return valve
• expansion relief valve
The expansion relief valve must have a maximum 0.6
MPa (6.0 bar) opening pressure and be installed on
the incoming domestic water line as shown.
• mixing valve
A mixing valve must be installed when the factory
setting for hot water is changed. National regulations
must be observed.
• pressure relief valve
• expansion vessel
The expansion vessel (CM4) accomodates expansion
that results from heating the water inside the unit.
The expansion vessel must be connected between
the expansion releif valve (FL1) and the water heater.
The location of the expansion vessel should allow ac-
cess to recharge the pressure as and when nec-
cessary.
