Product Presentation
1. Programming of automatic cycle “comfort temperature”,
“reduced temperature”, the principle of programming is similar to
EG100.
2. LCD screen
3. Facility for permanent override of “comfort temperature”,
“reduced temperature”, or “anti-frost”
4. Adjustment of the reduced temperature setting
5. Display of setting (comfort or reduced)
6. Display of state of output
7. Adjustment of the comfort temperature setting
Main Characteristics
•
Simplified summer/winter time setting
Summer/winter time setting is obtained by pressing two separate
keys
•
No loss of program in event of unlimited power failure
Loss of time setting only, program still in memory
•
Override
• Permanent: “comfort, reduced, anti-frost” temperature setting:
• With automatic return to: “comfort and reduced” temperature
setting:
•
2 wires link
Between the probe and the unit, this enables the easy
replacement of the ambient thermostats in an existing installation
•
Display Mode
Allows program to be checked without risk of alteration
•
Groups of days
Days can be grouped in order to save program steps (so, a
common setting for several days counts only as 1 program step)
Working Principle
The programmable thermostat regulates the heating thanks to 2
temperature settings: “comfort” and “reduced”, according to a
program established by the user; in cases of long absence, it is
possible to maintain an anti-frost temperature.
