The heating control thermostat is user adjustable
from 55°C to 85°C. In order to provide an
additional level of safety there is a high limit
thermostat which has a cut off point of 110°C;
this is factory set and is not adjustable. The high
limit thermostat is located under the control
panel to the left hand side, press button to reset.
As standard the panel is fitted with two on/off
selector switches to control hot water and central
heating. These switches can be replaced by the optional two channel digital
programmer, instructions for use are provided in the main boiler handbook.
