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.

• CH = Central Heating
• HW = Hot Water

Manual switch
Fig. 3: Manual switch
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).

WARNING!
Danger to life due to electric shock!
Improper assembly and installation of the device may result in life-threat-
ening electrical voltages.
− Have assembly and connection performed by a qualified electrician only.
WARNING!
Danger due to insufficient wire cross-section!
If wires with an insufficiently large cross-section are used, short circuits or
fires may occur.
− For the flexible wires, only use terminals with a maximum cross-section
of 4 mm².

Installation
Electric connection and installation
The device is mounted on the wall. If mounted on the wall, the connection wires either come directly out
of the wall or they are routed to the device on top of the wall.
In general, the following instructions apply to both connection wire options.
Where there are differences, the corresponding installation type is specified
before the instructions.
WARNING!
Danger to life due to electric shock!
Improper assembly and installation of the device can lead to life-threatening
electrical voltages.
− Have assembly and connection performed by a qualified electrician only.
16

NOTICE!

Selecting the wrong installation position can result in material damage to any
wires in the wall.
− Make sure that there are no wires in the wall at the installation position.
Personnel:
• Qualified electrician
Special tool:
• Power drill
• Drill
• Flat-head screwdriver
• Phillips screwdriver
Prerequisite:
• The terminals for the flexible wires have a maximum cross-section of 4 mm².
