When there is a fault that prevents correct operation, e.g. failure of the temperature-
control sensor, the display reads “ --- ” in place of the relevant temperature reading
(from internal or external sensor).
• In case of sensor failure when Thermo X is in WINTER-HEATING mode, the
relay will go on for 10 minutes every 4 hours to prevent the system from
freezing
• In case of sensor failure when Thermo X is in SUMMER/AIR-CONDITIONING
mode, the relay will stay permanently off
