6.3.2
Standby mode
The regulator goes to standby mode if the three communication objects "Comfort Mode",
"Night Mode" and "Frost/heat protect" are low. The "Actual setpoint" in this mode will be
set to "Base setpoint" + "Reduced Heating in standby mode". The "Actual setpoint" is set
to: 21ºC + (-1.0ºC) = 20ºC for the parameter settings shown in Figure 9.
For the cooling system in standby mode the "Actual setpoint" is set 1 degree higher than
in comfort mode: 21ºC + 2ºC + 1ºC = 24ºC
6.3.3
Night mode
The regulator will go to night mode if only the “Night Mode” object is set high. The
temperature setpoint for the heating and cooling systems will change according to the
parameters "Reduced Heating in Night mode" and "Increased cooling in Night mode".
For the heating system the “Actual setpoint” is set to: 21ºC + (-3.0ºC) = 18ºC with the
parameters shown in Figure 9. For the cooling system the "Actual setpoint" will be: 21ºC
+ 2ºC + 3ºC = 26ºC
6.3.4
Frost/Heat protection
The Frost/Heat protection regulator mode will set fixed temperature setpoints for the
heating and cooling regulators. The heating system is turned on if the temperature falls
below 10ºC – 0.5ºC hysteresis. The heating system is turned off if the temperature goes
above 10ºC.
The cooling system will turn on if the temperature goes above 35ºC + 0.5ºC hysteresis
and will turn off again when the temperature goes below 35ºC.
The user panel LED indication for the local temperature adjustment will be turned
off when the regulator goes into standby mode. The LED indication for the active
heating- and cooling system will still be active.
The user panel LED indication for the local temperature adjustment will be turned
off when the regulator goes into night mode. The LED indication for the active
heating- and cooling system will still be active.
The user panel LED indication for the local temperature adjustment will be turned
off when the regulator goes into Frost/heat protection mode. The LED indication for
the heating- and cooling system alternates between heating and cooling every
second.
