12.4 Operating temperatures
XSE 602 permits configuring, with different desired temperature values, the various operating modes
available, namely :
– 5 NORMAL = operation with compensated control to provide comfortable ambient
temperatures (daytime or when building occupied)
– 2 SETBACK = operation with compensated control to provide economical ambient
temperatures (at night or when building not occupied)
– FROSTPROT = operation with control providing safety temperature (holidays or when building
not occupied)
– 2 FLOW = operation with control providing flow temperature at a constant value (heating
curve not taken into consideration)
– OFF = valve closed and pump idle
12.
5 Minimum and maximum flow temperature limits
When the desired flow temperature reaches one of its limit values it is kept constant at that value.
eg : - minimum limit to avoid circulation of cold air in fan coils
- maximum limit to avoid dangerous overtemperatures in panels
Warning : The maximum limit temperature does not substitute observance of the safety measures
in force.
12.
6 Actuator run time
This is the time taken for a complete run (open / close) of the valve actuator necessary for correct
control operation.
12.
7 Ambient authority
When ambient sensor B3 is connected, the controller is able to adjust the desired flow temperature
in accordance with the ambient authority set.
When sensor B3 is not connected, the adjustment is made only in the Setback / Frostprot modes
using the value of the ambient temperature calculated in relation to the time constant.
– POSITIVE: increase of flow temperature for each °C difference between measured room tempe
-
rature and the desired toom temperature, when the measured room temperature is
below the desired room temperature
.
– NEGATIVE : reduction of the flow temperature for each °C difference between the measured room
temperature and the desired room temperature, when the measured room temperature
is higher than the desired room temperature
..

8 Eco Off
For each heating zone, permits excluding heating when weather conditions do not require it :
– NO = disabled
– YES = enabled
Functions only in Normal /Setback modes for :
Tf

- Ta
ac
≤ 2°C = Eco Off On
Tf

- Ta
ac
≥ 4°C = Eco Off Off
where : Tf
c
=calculated flow temperature
Ta
ac
=actual or calculated ambient temperature
12.9 Operating programmes
Choice of operating programme for each heating zone according to requirements :
– 24 HOUR 1...7; – 7DAY1 - 2, – NORMAL 1...5; – SETBACK 1 - 2; FROSTPROT;
– FLOW 1 - 2; OFF
In place of programme the following may appear :
– SUMMER = controller is in summer period
– HOLIDAY = controller is in holiday period
– SPECIAL = controller is in special period
– REMOTE EXTENSION = “Remote Extension” period has been activated.
To cancel this function, on first page press ← and → keys together
– REMOTENORMAL 1 = remote control “R” is in “Normal” position
– REMOTESETBACK 1 = remote control “R” is in “Setback” position
– REMOTE FROSTPROT = remote control “R” is in “Frostprot” position
– REMOTE OFF = remote control “R” is in “Off” position
– REMOTE+2c = remote control “R” is in “TAd + 2°C” position
