Mounting
The reversing valve (QN10) is always installed between
the heat source and the hot water accumulator/rest
of the system. In the starting mode, without control
voltage, the reversing valve must be open to the rest
of the system. When control voltage is applied the re-
versing valve opens to the hot water accumulator.
Installing the valve motor
Example installation:
1. Ensure that the depression, in the shaft (1a) and
the shaft on the valve (1b), are at 12 o'clock with
the port up. In this example ▲ and ■ are open while
● to begin with is closed.
2. Ensure that the knob on the motor is turned all the
way to the left.
3. Turn the knob to the right to close ▲ and open ●.
