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
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 2 CH setpoint.
The request is unlocked if the calculated
setpoint is greater than the temperature
given by the sum of the zone 2 CH setpoint +
ECO shutdown hysteresis CH Zone 2.
This parameter takes effect if the ECO
function is activated via the ''ECO'' button or
via time programming.
Defines the level for reducing the control
setpoint for zone 1 heating when the room
thermostat contact is open.
Only applies if the CH demand type
parameter is set as a constant setpoint (can
also be set by the user).
Defines the level for reducing the control
setpoint for zone 2 heating when the room
thermostat contact is open.
Only applies if the CH demand type
parameter is set as a constant setpoint (can
also be set by the user).
