Minimum ON period (t)

In order to prevent frequent relay switching, this parameter can be used

to specify the minimum ON period. This period specifies the minimum

amount of time for which the relay is to remain on when a request has

activated the relay.

1. The + and - buttons can be used to set this parameter in a range of

20 seconds to 500 seconds (8.3 minutes) in steps of 10 seconds.

2. S is used to save the set value.

A minimum ON period of 20 seconds is set in our works.

Sensor offset (o)

The measured actual temperature can be displaced by ±3.0 Kelvin by

means of this parameter. This correction can be used to compensate the

measuring deviations which arise though the unfavorable placing of the

room temperature controller.

1. The + and - buttons can be used to set the parameter.

2. S saves the parameter.

The value set here is always applied to the respective active sensor

(external or internal temperature sensor, depending on the operating

mode selected) which is used for the temperature control.

The sensor offset is set to 0.0 Kelvin in our works.

Heating optimisation (E)

The heating optimisation determines the temporal behaviour of the room

on the basis of the past heating processes and calculates the required

derivative action time which is necessary in order to reach the desired

setpoint temperature on time.

The automatic heating optimization can be activated (On) and deactivated

(OFF) here. If the heating optimisation is deactivated, switching is carried

out exactly as specified in the time program.

1. The + button can be used to set the heating optimisation to On and

the - button to OFF.

2. S saves the setting.

The heating optimisation is activated (On) in our works

Gradient for heating optimisation (r)

The current gradient which is used to calculate the derivative action time

can be checked under this menu item. The time required to heat the room

by one Kelvin (1K) is displayed here in minutes.

If the heat optimisation is activated, this gradient is always recalculated

during a transition from a lowering phase to a comfort phase.

The heating optimisation is set to a gradient of 15 minutes per Kelvin in

our works.

Summertime regulation (S)

The summertime regulation with which the changeover from normal to

summertime and vice versa is to be calculated can be selected here. The

room temperature controller differentiates between Central Europe and

Great Britain.

1. The + and - buttons can be used to change to one of the operating

modes listed below.

2. S activates it.

Information on the summertime function

If the summertime function is deactivated (OFF), an automatic

changeover of the time is not carried out. Note that the time has to be

changed over manually in this case.
