Manual Overrides

The heating circuit macro supports the following manual overrides:

Override

Priority

summer switch

1

highest

Connect the input „SummerSwitch“

0 = auto,

1 = summer

heating off in summer

setpoint summer = RMT-06

extended operation switch

2

Connect the input „DayExtension“

0 = auto,

1 = extended operation

heating on during extended operation

setpoint day = RMT-04

holiday switch

3

Connect the input „HolidaySwitch“

0 = auto,

1 = holiday

heating off during holiday

setpoint holiday = RMT-06

wall module

4

Add the macro RSB_TF22 and connect „ContrPtAdj“ and „ManSwCond“

See RSB_TF22 macro description

setpoint day = RMT-04

setpoint night = RMT-05

time schedule

5

lowest

Connect and configure a time schedule or a datapoint to the input “RoomTempSp“

Higher value during occupied- and lower value for un-occupied periods

If you do not use a time schedule, configure the datapoint as a setpoint, to avoid manual alarm, when you change the values.


Summer and holiday switches

When either the holiday or the summer overrides are active, the room temperature setpoint is defined by the parameter RMT-06, which has 5 °C by default.

During holidays and summer the heating circuit starts to control at outside air temperatures below the frost protection limit.

Extended operation button

When the extended operation button "DayExtension" is pushed during un-occupied periods or holidays, the heating circuit is set in to manual occupied mode.  

The extended operation button is locked when

In manual occupied operation, the room temperature setpoint is defined by the parameter RMT-04, manual occupied setpoint (day). This manual override time will last for the time period RMT-07.

This timer will be reset as soon as the room temperature setpoint of the time schedule switches to occupied.
After this period has elapsed, the heating circuit will return to the automatic mode again.
If the parameter RMT-07 is set to the value of zero, the function will be active only as long as the extended operation button contact is closed. A possible usage scenario with the setting equal to zero is to use an external flush-mounted timer.

Wall module

The preferred wall modules for heating circuits is TF22 or CLCM3T111.

See the macro RSB_TF22 macro description for functions and parameter settings.
