Olympia 4 pieces Heating thermostat

4 pieces of extremely compact, energy-saving controllers that can save up to 30% on heating costs. They feature valve protection, a very stable housing design, and are no larger than a standard thermostat head.

These controllers operate very quietly and are easy to use with a rotary knob and a thread connection of M30x1.5.

They fit many well-known valve bodies, including Heimeier, Danfoss, Honeywell Braukmann, Honeywell MNG, and Oventrop from around 1996.

Features include the ability to set 4 heating and savings times, flexible temperature settings for each switching cycle, and a weekly program that can be set for Monday to Sunday, Monday to Friday, or individually for each day. They also have automatic summer/winter time adjustment, frost protection, vacation function, and window-open detection.

Additional features include valve protection, a frost protection function, a scale of 0-24 hours (in 6-hour increments), child lock, offset function for temperature setting, an intelligent boost function in the control algorithm, a factory preset basic program, a battery change indicator, a snap-on closure, and a housing material made of white ASA. The weight of the thermostat is 108 grams.
