Digital Timer - Webasto Telestart T91 Installation Instructions Manual

Telestart T91 / T100 HTM
Switching input for analogue connection of heater controls
In addition to the Telestart, a digital timer or
a pushbutton switch can be installed.
Caution:
The digital timer and the pushbutton switch
transmit differing signals to the Telestart re-
ceiver!
The signal input must be adapted to the ap-
propriate heater control!
By default, the signal input of the Telestart
receiver is tuned to the digital timer!
The included ESVT adapter must be adapted
to the existing installation situation (heater
controls and heaters) accordingly by "pin-
ning it in".

Digital timer

When the heater is activated (by pressing the
instant heat button or by the start of a preset
heater operating time) the Telestart receives
a continuous plus signal from the digital tim-
er during the entire operating time.
Upon deactivation of the heater (by pressing
the instant heat button or when the end of
the operating time preset on the digital timer
is reached), the positive signal is cut off and
the heater is switched off.
Pushbutton switch
Upon switching on or off using the pushbut-
ton switch, the Telestart receiver receives a
short plus signal.
For the Telestart to be able to recognise this
signal, the switching input needs to be set to
"pushbutton switch".
The heater does not switch on if the switch-
ing input is not changed over to "pushbut-
ton switch". Instead, it enters the post-
operation stage and then switches off.
