Spring V11 Hot Water Instruction Manual

The temperature of the water can be monitored by pressing enter twice after
turning the unit on.
To control whether the heater is on or off while pumping, press and
hold down and enter to go into the set up menu. Press enter until heater
message is displayed.
Press up or down to change between on or off. Off will prevent the heater
from heating the water whilst the controller is on. Press enter again to
turn frost protection on and off, using the up or down buttons.
Press enter again to set the temperature at which the frost protection
turns on. Adjust value with up and down, e.g. to set heater to come on at 2
degrees centigrade set controller to 2. Note: if you set Ftp too high your
heater may turn on when you do not need it. ie when there is no danger of
the water freezing.
Press enter again to adjust the speed of the pump recirculation when frost
protection is working. Set pump flow rate using up and down. Note: for
Webasto heaters, set flow to 10. Other heaters may require a higher flow. Set flow
to the minimum possible. Faster flow will discharge your battery more quickly.
Once you have reached the last configuration press enter to set.
