V
Fit the diverter valve in the return pipe between the solar storage cylinder (
Æ
Fig. 4) and the
boiler.

Function of valve switch
Use the "MAN" (manual,
Æ
Fig. 5, item 2) setting for filling, bleeding or draining the system or as
the safety setting when there is a power failure. In the "MAN" position, the valve actuator is in the
centre position. This allows even flow of the fluid through both outlet connections.
V
For normal operation, set the switch to "AUTO" (
Æ
Installing the temperature sensors
There are 2 temperature sensors supplied with the valve. They can be used as cylinder temperature
sensors or pipe contact sensors (
Æ
Table 1, page 6).
V
Apply heat conducting paste (
Æ
Fig. 5, item 6) to temperature sensor S3 (
Æ
V
Fit temperature sensor S3 using retaining plate (
Æ
Fig. 5, item 4) and spring strap (
Æ
Fig. 5, item
7) to the return pipe approx. 20 cm upstream of the diverter valve.
V
Provide temperature sensor S3 with insulation at least 20 cm long (
Æ
Fig. 5, item 3).
V
Fit temperature sensor S6 in the position provided on the cylinder (see installation instructions
for cylinder).
Observe the connection markings on the diverter valve.The valve in Fig. 4 allows fluid
to flow from AB to B when de-energised. Once the set temperature difference is
reached, the valve switches over to divert the flow from AB to A.
Caution:
Risk of system damage if the valve positioner casing is damaged.
V
Use spanner on union nuts not on valve body.
