Description of elements and LEDs
This is a unit designed to control up to four independent hot water heating circuits. Based on
the requirements of the thermostats in each room, the given thermoelectric drive, boiler and
circulation pump are switched on.
When one of the connected thermostats (PT1 PT4) requests heating, the thermovalve for the
given circuit opens and after one minute the circulation pump and boiler are switched on (indicated
by the RE diode). The pump and boiler are switched off if none of the connected thermostats
require heating (open contact).
It is possible to use external control to switch off all circuits (see page 2). For example, it is possible
to use a time switch to save energy on heating when people are not present.

Circuit output (t.e. actuators)
(e.g. SEH01-NC)
The external control terminal (EXT) is used for the possible connection
of a timer or other potential-free switching element. If this contact is
open, all output terminals are switched off (the requirements of the
thermostats are not taken into account).
If this contact is not used, the terminals must be bridged with
a wire jumper.

Power terminal 230 V AC
Thermostats with potential-free contact can be used (e.g. PT01,
PT10, PT21, PT22, PT23, PT32, PT32 GST).
