Tips on Getting Started
Your heating system provides central heating and domestic hot water heating in
conjunction with a domestic hot water tank.
The timer of the control unit switches over between ”normal room temperature”
and ”reduced room temperature” at the required times.
1. Normal room temperature
for the times you spend at home and
require a comfortably warm room
temperature (e.g. 68 ºF / 20 ºC).
2. Reduced room temperature
at nighttime or for the times you
spend away from home. To save
energy, a temperature which is lower
than the ”normal room temperature”
is normally selected.
In the factory setting, ”frost
protection at 37 ºF / 3 ºC” is
selected.
Times and duration of the two room
temperatures can be set via the
programming unit.
You can set the required temperature
value for both the ”normal room tem-
perature” and the ”reduced room tem-
perature”.
The timer of the control unit activates and deactivates the domestic hot water
supply at the required times (applicable to boiler with domestic hot water tank
only).
1. Domestic hot water heating takes
place
for the times you spend at home and
require hot water for your daily
requirements (e.g. for showering).
2. Domestic hot water heating does not
take place
at nighttime for example.
Times and duration of domestic hot water
heating can be set via the programming
unit.
The domestic hot water temperature
can be set according to your personal
preference up to 140 ºF / 60 ºC.
The DHW recirculation pump (if
installed) ensures instantaneous avail-
ability of hot water.
