The energy saving function (Economy) is a fast acting
mechanism which turns off the heating system as soon
as heat is no longer required. This allows economical
operation throughout the year, as the heating system does
not need to be turned off manually, particularly during the
switchover periods.
The basis for this process are the values of the average
external temperature and the current room temperature
setpoint.
If the average external temperature increases above the
current room temperature setpoint the heating system is
turned off.
Turn off point of heating system: TEaver= TRt
If the average external temperature falls by more than 2° C
below the current room temperature setpoint the heating
system is turned on.
Turn on point of heating system: TEaver = TRt - 2° C
With an active daily automatic heating limit (DHL), the
heating is automatically turned off or reduced.
When “Summer” is selected with the selection switch for
type of operation, the display can show either “Economy”
or “Summer” depending on the dampened external
temperature and the Summer/Winter switchover
temperature.
“Economy” and “Summer” operation function in the same
way.
The “Economy” function is a short-term measure, the
“Summer” function is a long-term measure, as the
dampened external temperature is used for this function.
The Summer/Winter switchover temperature
(parameter 53) is the criteria for automatic switchover of
the heating system between Summer and Winter
operation, exclusively for the heating circuit.
By altering the switchover temperature the relevant
annual phases are either shortened or lengthened. This
conversion only affects the heating circuit.
Switchover temperature:
Increase: Switchover to Winter operation earlier
Switchover to Summer operation later
Decrease: Switchover to Winter operation later
Switchover to Summer operation earlier
Heating OFF (Winter to Summer) TEdamp > DHL + 1° C

By activating the room sensor in the heating engineer’s
level, parameter 130 ➩ “On” the integral temperature
sensor is used as guide value for the heating circuit. The
thermostat function activates or deactivates the heating
circuit. If the current room temperature exceeds the normal
set temperature by the temperature set at the thermostat,
the heating circuit is switched off and the display shows
“Economy”. If the room temperature is lower than the
temperature set at the thermostat,
the heating circuit is reactivated and the type of operation
changes from “Economy” to the type of operation set.
Note: Pump protection function
If the Summer/Winter switchover or Standby
function is activated, the heating
circuit and hot water pumps will be activated
one by one for 30 seconds every Friday
from10.00 hrs.
