The “thermio™ eco B1” timer is an analogue single-channel synchronous timer that switches con-
nected loads on and off at defined times.
The “thermio™ eco B1” timer is used to regulate a heating circuit. It can be connected to a water cir-
cuit, a heating circuit or a joint water/heating circuit. A joint water/heating circuit is then regulated
jointly. Simultaneous regulation of, for example, central heating and hot water is implemented using just
one switching output.

The “thermio™ eco B2” timer is an analogue two-channel synchronous timer that switches connected
loads on and off at defined times.
The “thermio™ eco B2” timer is used to regulate two heating circuits. Hot water or heating circuits can
be connected and regulated independently of each other in the OFF and CONST. operating mode. In
TIME operating mode, the two heating circuits are regulated together, according to the setting of the ON
or OFF tappets. Individual regulation of, for example, central heating and hot water is implemented using
two independent switching outputs.

The “thermio™ eco B1” single-channel timer has one manual switch and the “thermio™ eco B2” two-
channel timer has two manual switches, one for each channel.
In the “thermio™ eco B2” two-channel timer, the two channels can be set independently of each other.
If a channel is switched on, the corresponding LED lights up (Fig. 1/2 and Fig. 2/2, 7).
