Operating instructions RC30 programmable room thermostat • Issue 02/2006
Summer mode
A changeover threshold for summer/winter changeover is entered
in the RC30 (factory setting 17 °C). When the adjusted outside
temperature exceeds the changeover threshold, the heating
system switches to summer mode (DHW heating only).
If you require heating for a short period in summer mode:
Press the "Day mode" button to switch to normal heating mode for
a short time (see Chapter 7.2.2 "Selecting manual mode",
page 23).
Press "AUT" to return to automatic summer mode.
Winter mode
When the adjusted outside temperature falls below the
changeover threshold, the heating system switches to winter mode
(heating and DHW heating).
USER NOTE
For summer/winter changeover, your installer must have set up
outside temperature dependent control (see "Outside
temperature dependent control", page 6).
Summer/winter changeover does not apply to room temperature
control.
