With Timing Switch and Room Temperature Controller, Type 30277

Operating instructions

2

Speed selector switch

The signal lamp indicates the current operating status of the equipment:

3

Operating mode selector switch

*If the speed selector switch is in the "Auto" position, the "Day" mode of operation is active..

4

Temperature setting, day mode

For setting the required room temperature during the "day mode" phase.

5

Night mode, temperature lowering setting

For setting the required temperature reduction during the night mode
phase.

6

Timing switch

For setting the times at which the day/night mode is switched over. For a
description of this, see timing switch operation (Chapter 4.1 ff)   

Releasing the motor malfunction (thermal contact triggered)

A malfunction can be released via the zero reference position of the speed
selector switch. If the malfunction has not been eliminated, the 
malfunction signal will reappear (see page 9).

auto

Automatic speed change-over regardless of the room temperature

set-point and actual value.

Day

Room temperature regulated to the day temperature which has

been set

Night

Room temperature regulated to the lower temperature which has

been set

Timer

The integrated timer switches over between the day temperature

and the lower temperature

* Continuous fan operation at the set speed level

Fig. 4: Setting the differential gap

Differential gap of the room temperature controller

If necessary, the differential gap (hysteresis) of the temperature controller
can be changed:

We recommend a setting of approx. +/- 1 Kelvin.
