Diverting valves (Y21, Y22)
230 V 1N~.
2.5 m cable 1.5 mm²
When pole A18 or X7/24 is supplied with power, l ow should be to the hot
water system. When they are not supplied with power, l ow should be to the
heating circuit.
The diverting valves are connected to the following terminal blocks:
(Y21) Diverting valve 1
Relay output
pole A18
Phase
pole A19
Zero:
pole A20
(Y22) Diverting valve 2, expansion card X7
Relay output
pole 24
Phase
pole 25
Zero:
pole 26
Check the function by test running the diverting valve in menu
“Installer/
Service/Function test” in the control system.
In the “DOWN” position on the function menu, port
▲
should be open (turn
the knob on the motor clockwise, CW). In the “UP” position, port
■
should
be open (turn the knob on the motor counterclockwise, CCW).
The motor is i tted to the diverting valve by a screw. To unfasten the motor:
remove the knob by pulling it off, unfasten the screw and remove the motor.
To prevent faults, turn the actuator and diverting valve to the starting position
for i tting as shown in the i gures. Pull out the knob on the actuator and turn
to the central position.
Port
●
should be completely open; ports
■
and
▲
should be partially open.
Ensure that the groove in the white shaft coupling is in position as shown
in the i gure. The diverting valve and actuator can then be i tted together as
shown in the i gure, or turned in 90-degree steps relative to each other.
If ports
▲
and
■
have been shifted during the hydraulics connection, the
motor can be reconnected to change its direction of rotation. This is done
using two jumpers inside the motor.
NOTE:
the direction of rotation cannot be changed by swapping the
black and brown cables.
