C505G 16A Electric Floor Heating Thermostat — Programmable NTC Thermoregulator Controller for Gas Boiler Server, Easy to Use

Compact programmable thermostat for electric underfloor heating, compatible with NTC sensors and gas boiler/server systems. Operates in automatic or manual mode — in automatic mode it follows the weekly program to save time and reduce energy loss. Weekly programming: configure up to 6 time periods on working days and 2 time periods on rest days. Choose from three scheduling patterns: 5+2, 6+1 or 7 (the first number denotes working days, the second denotes rest days). Temperature adjustment: display temperature offset can be set within -8~8. Adjustment accuracy is 0.5. Differential (hysteresis) is adjustable in the range 0.5~5. Antifreeze and memory: antifreeze function automatically starts heating when temperature falls below 5 to prevent cold damage. The unit automatically saves previous settings after a power failure, so no reset is required. Linkage delay: default delay is 5 minutes, configurable from 0 to 5 minutes.
