Caution when using these parameters in combination with the parameters "Zone 1 CH ECO setpoint reduction", "Zone 2 CH ECO setpoint
reduction" of this menu and "Zone 1 Offset", "Zone 2 Offset" of the menu "Outdoor temperature", as it may inhibit the CH demand in an unintended
manner.

Description
Sets the temperature that will be subtracted
from the actual setpoint for heating zone 1
when the "ECO" mode is activated.
If the parameter "CH Request type " is set to
"Only OTC", it defines the level for the
reduction of the control setpoint for zone 1
heating, if the room thermostat is closed (it
can also be set by the user).
Sets the temperature that will be subtracted
from the actual setpoint for heating zone 2
when the "ECO" mode is activated.
If the parameter "CH Request type " is set to
"Only OTC", it defines the level for the
reduction of the control setpoint for zone 2
heating, if the room thermostat is closed (it
can also be set by the user).
If set other than 0 and when the "ECO" mode
is active, the CH demand is inhibited when
the calculated setpoint is lower than the
temperature set on the zone 1 CH setpoint.
The request is unlocked if the calculated
setpoint is greater than the temperature
given by the sum of the parameter zone 1 CH
setpoint + ECO shutdown hysteresis CH
Zone 1.
This parameter takes effect if the ECO
function is activated via the ''ECO'' button or
via time programming.
