Setting the Central Heating Temperature (continued)
Operation with room temperature thermostat
If no outside temperature sensor is connected,
but a room temperature controller is.
If the required room temperature is not achieved,
ensure the boiler water temperature setting is sufficiently
high. In the delivered condition, the boiler water
temperature is set to 158°F (70°C).

Setting the room temperature
An outside temperature sensor must be connected for
weather-compensated operation and a jumper must be
installed on terminal 96 ‘L’ and ‘1’. (see the installation
instructions).
In the delivered condition, a parameter value of 20 (or
68 if display converted to °F) is set for central heating.
Should you wish to set a higher room temperature,
increase the parameter value;
reduce it for a lower room temperature.
Refer to ‘setting the heating curve’ on page 12.
