Description of function
The “thermio™ eco C1B” and “thermio™ eco C7SB”
multi-tariff timers are programmable timers with a fuseprotected, two-pole on/off switch. Switching times can
be programmed for both devices, during which connected loads are supplied with power.
In addition, the devices have an
[ADV]
button and a
[BOOST]
button. These buttons can be used to change
the current state of the device, regardless of the programming, or to activate the device for a specific time.

Wire cross-section
WARNING!
Danger due to insufficient wire cross-section!
If wires with an insufficiently large cross-section are used, short circuits or fires may occur.
− Only use terminals with a cross-section
between 1 mm² and 2.5 mm² for flexible
wires.
EN
19
Page 20
WARNING!
Risk of injury due to uncontrolled behaviour of connected loads!
− Before starting the device, check whether
the connected load could cause hazardous situations for persons.
NOTICE!
