The “thermio™ eco B1” timer is an analogue single-channel synchronous timer that switches connected 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 circuit, 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.

Manual switch

Fig. 3: Manual switch

The “thermio™ eco B1” single-channel timer has one manual switch and the “thermio™ eco B2” twochannel 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).

Page 16

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.

Page 17

NOTICE!

Danger of material damage to wires in the wall!

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.

Removing the mounting plate

Fig. 4: Undo the mounting plate from the device housing

1. Undo the safety screw on the device housing (Fig. 4) with the flat-head screwdriver.

Page 19

The screw in the mounting plate is captive, in other words you can loosen it but you cannot remove it.

Page 20

2. Remove the mounting plate.

through

Page 21

3. When selecting the installation position, make sure that a distance of at

least 4 cm is left free below the mounting plate to leave space to open the cover and undo the safety screw.

Mark the hole pattern from the mounting plate (Fig. 5/2) onto the wall.

4. Drill holes at the points you marked.

5. Insert suitable wall-plugs for the screws into the holes.

6. Connection wires directly out of the wall: Thread the connection wire into the device through the

cable feed-through (Fig. 5/3).

7. On-wall connection wires: Break out the necessary defined breaking point (Fig. 5/6) and thread

through the connection wires.

Page 22

Connecting

9. Strip insulation from the connection wires.

• Stripping length: 8 mm

10. The housing is doubly insulated (protection class 2) so no earthing con-

nection is necessary. To improve the appearance, insert the earth connection into the earth terminal.

Insert the earth connection wires into the earth contact (Fig. 5/4).

To ensure that the wiring is correct, consult the operating manual for the heating system in use.

Page 48

1 Minute hand 2 Dial with tappets 3 Indicator marker 4 Hour hand

NOTICE!

Risk of material damage due to turning anti-clockwise!

Turning the dial or the clock hand anti-clockwise can result in material damage to the timer.

− Make sure to turn the dial and clock hand clockwise only.

To roughly set the time, turn the dial (Fig. 19/2) clockwise until the indicator marker (Fig. 19/3) points to the current time.

In 12 hour display: 6:00 = 6.00 (a.m.) and 16:00 = 4.00 (p.m.)

The timer does not distinguish between summer and winter time. As a result, you have to set the summer and winter time manually by adjusting the current time.

Page 49

2. To finely adjust the time, turn the minute hand (Fig. 19/1) clockwise until the time indicated by the

indicator marker (Fig. 19/3) matches the current time.

The dial and the clock hand rotate together with the current time.

Fig. 20: Setting the tappets

Page 50

1. Each tappet represents 15 minutes of switching time.

If the tappets are pushed inwards, the heating system is switched off during that time; if the tappets are pushed outwards, the heating system is switched on during that time.

Push the tappets to OFF (Fig. 20/1) or ON (Fig. 20/2), according to your desired switching times.

2. To activate the timer, switch the manual switch to the TIMED operating mode.
