Only heat pump 1
may be connected
to the 3-way valves
(Y21).
Heat pump 1 is connected to 3-way valves for changing between the upper
and lower tanks. Heat pumps 2 and 3 are connected directly to the lower
tank for supplying radiators.
Ensure that the ports on the 3-way valves (Y21) are set as in the schematic
diagram. The ports
●
must always be connected to heat pump 1.
If it is necessary to swap ports (
■
and
▲
), two jumpers in the actuator
must be reconnected. See the chapter on Electrical installation for more
information.
Note that the last heat pump in a series connection must be in the
terminated position, i.e. DIP switch 2 on the last heat pump must be in
the ON position and the other heat pumps in the OFF position. For more
information, refer to the Installation and Maintenance instructions of the
respective heat pump.
The 3-way valves (Y21) and the circulation pumps (G11), (G12) and (G13) are
CTC accessories.
Also refer to the "Heat pump" section in the "Detailed Menu Descriptions"
chapter (Installer/Settings/Heat Pumps 1-3).
