Therefore for temperature regulation the internal temperature sensor of the room
controller should be primarily used.
The Input E2 can only be used in the range from a NTC 5 kOhm to a NTC 10 kOhm
temperature sensor.
To get a more stable value at lower temperatures (higher resistances) a filter-FBox
(Filter T1) should be used.
This can be done by placing of “TempE2”-symbol from the “symbol editor” and con-
necting it with the “Filter T1” FBox.
The Filter “Time constant” should be set to 10 seconds to get a good result.
The temperature value will be displayed in the room FBox in the section “more
informationen” or it can be read out from register 69.
PWM cycle time for Y1/Y2 in s (register 11)
PWM cycle time for the valve outputs Y1 and Y2 in seconds. Where Y1 and Y2 are
used as a 3-point output, this parameter holds the motor running time.
