TECHNICAL CHARACTERISTICS
MODES DESCRIPTION
- Electronic thermostat with night reduction mode for water floor heating
systems controlled by actuators.
- External pilot wire for night reduction, equipped with a switch to select
comfort, reduction or clock mode.
- Possibility to regulate either the floor or room temperature, or combined
(in this case, the floor sensor is used as temperature limiter)
- Silent (triac output), to be connected directly to actuators (see connecting
drawing on the installation sheet) or to our Modular connecting system.
(In this case please refer to the connecting box datasheet)
LED INDICATOR
Red: - Heating indication
Green: - reduction mode by clock (pilot wire)
Orange: - Heating during reduction mode by clock (pilot wire)
Red blinking: - 0.5 second cycle => Internal & external sensor failures
- 1 second cycle => Internal sensor failure
- 2 seconds cycle => External sensor failure
