Runback Timer
1. Description RX TI RB
The runback timer allows the heater to be operated for a pre-
set period of time. Depending on the presetting, the timer
switches off after the preset time period has elapsed (stand-
ard mode), or else switches to another operating mode (com-
fort mode). The settings that can be selected range from 0.5
– 4 hours (in 0.5-hour increments).
1.1 Standard Mode
The heater is switched on for a preset operating time
immediately after the Start button has been pressed. The
room temperature is regulated in accordance with the
thermostat setting on the heater. After the preset time period
has elapsed, the timer switches the heater off. If required, the
program can be reactivated by pressing the Start button.
1.2 Comfort Mode
The heater is switched on for a preset operating time immedi-
ately after the Start button has been pressed. The room tem-
perature is regulated in accordance with the thermostat set-
ting on the heater. After the preset time has elapsed, the
timer switches to the setback mode and lowers the room
temperature set on the thermostat by 5 °C for the next 24
hours. After these 24 hours have elapsed, the frost protec-
tion setting is active. The thermostat of the heater regulates
the room temperature to a value of 5 °C. This setting is main-
tained.
2. Setting the Timer
Before the runback timer is installed, the heater operating
time and operating mode must be set. Four miniature
switches are arranged in a recess on the underside of the
cassette for this purpose.
2.1 Setting of the Standard Mode

5. Operational Performance in the Standard Mode
After the preset time period has elapsed, the timer switches
off. The program can be restarted by pressing the Start but-
ton. If you wish to prematurely terminate the preset program,
press the Start button. The heater is switched off.
6. Operational Performance in the Comfort Mode
After the preset time period has elapsed, the timer automati-
cally switches the thermostat to a temperature which is 5 °C
below the thermostat setting (setback mode). The heater will
then maintain this temperature for another 24 hours. At the
end of these 24 hours, the timer switches the thermostat to
the frost protection temperature at approx. 5 °C (frost protec-
tion setting).
Pressing the Start button allows you to move to the next op-
erating mode, i.e. from the normal to the setback mode, from
the setback to the frost protection mode, from the frost pro-
tection mode back to the normal mode.
