Thermostatic By-pass Valve &
Thermostatic Heating Control Valve
The temperature increases by 5°C by each number displayed on the head:
0 = 40°C
1 = 45°C
2 = 50°C
3 = 55°C
4 = 60°C
5 = 65°C
6 = 70°C
To adjust the temperature push down on the plastic lock ring and rotate the head to the desired
number/temperature. Once the correct temperature has been selected push the lock ring back to
its original position to lock the head in place.
Zone Valve
The flow rate on the zone valve is adjusted by rotating the square face of the brass nut with either
a small adjustable spanner or pliers. When adjusting the zone valve the flow rate can be checked
on the heat meter (option 5 on the heat meter display) to establish when you have reached the
desired flow rate.
If the square faces of the brass nut are turned all the way to the top the valve is fully open. When
it is rotated all the way to the bottom the valve is fully closed.
