Nowadays, home type water heat pump system normally works without fan coil. This heat pump has summer mode (cooling) and winter mode (heating). In the heat pump control system, there is one thermo sensor connected. This sensor connected to main controller. If outside temperature more than 25-degree, system has signal pulse from the thermo sensor to switch heat pump to summer (cooling) mode. If outside temperature lower than 15-degree, system has signal pulse from the thermo sensor to switch heat pump to winter (summer) mode.  Those modes switch automatically done by heat pump control system. There is no relationship with thermostat.

However, to keep connected thermostats work in the same mode as water heat pump is extremely important and meaningful. Our thermostat system should work reversely in different mode. Winter time we should set higher degree of the room to make the room hotter. Summer time we should set the degree lower to make the room cooler.  Therefore, in the thermostat, there should be CO input contact. This contact is “Normally Open Contact”, dry contact. When the 230/24V signal pulse comes from the heat pump, base unit will switch to summer mode (cooling), and send this 230V/24V signal pulse to connected thermostats. When all thermostats get this 230V/24V signal pulse from wiring cetnre, all room thermostats will switch to the summer mode (cooling). If the room temperature higher than thermostat value, thermostat let the actuator open and let the cool water inside into room pipe system.

If there is no signal from heat pump to CO contact at wired 8 zone wiring centre, thermostats should work in winter mode (heating). At that time, if room temperature colder than thermostat value, digital programmable thermostats should let the valve open and let the hot water inside into room pipe system.

Electric floor heating thermostat is a kind of end control product, mainly used to control the temperature of electric floor heating equipment. It can set the switching machine or room temperature according to the need for time segments, mainly through the probe to achieve the accuracy of temperature adjustment. There are various types of electric floor heating thermostats, and different types of electric floor heating thermostats have different effects.

There are two main types of electric floor heating thermostat: mechanical and electronic, mechanical using sensitive gas membrane box or thermal bimetal sheet as temperature sensing elements, forming a temperature control switch of mechanical contact. This kind of thermostat in Europe and the United States more market, mechanical heating thermostat usually contact current is not more than 8A, suitable for water heating system control valve open and close. The electronic heating thermostat is a negative temperature coefficient thermistor (NTC), the relay contact control output, according to the size of the contact current to distinguish, the conventional specifications are 3A, 5A, 8A, 16A, 20A, can meet the water heating system and large load (400W below) of the electric heating system control requirements.

The electric floor heating room thermostat is usually installed on the wall of the rooms, and people can control the electric floor heating switch by setting the temperature on the thermostat. When the indoor temperature is lower than the set value, the thermostat will automatically turn on the electric floor heating equipment, so that the indoor temperature rises; When the indoor temperature is higher than the set value, the thermostat will turn off the electric floor heating equipment to keep the indoor temperature stable.

Due to the high frequency of use of electric heating equipment, long-term use may cause some damage to the equipment, and by using the electric heating thermostat, people can better control the switching time of electric heating equipment, avoid frequent opening and closing of the equipment, thereby extending the service life of the heating equipment.

Nowadays, People can use smart phone to control the room temperature, some even can be a voice controlled thermostats.

Electric floor heating thermostat has a high safety, it uses advanced temperature sensors and circuit protection system, can accurately monitor temperature changes, and automatically cut off the power in abnormal circumstances, to protect equipment and personnel safety. By precisely controlling the temperature, energy waste can be effectively reduced, carbon emissions can be reduced, and environmental protection has a positive contribution.
