Thermostats Installation Notes

When install the floor heating thermostat we should pay more attention to the f problems as follows:

1. Wall mounting, a height of 1.2 meters, in general which has the same level with Household electrical lighting switch .

2. Installed wall which is surrounded by the free flow air, without other sources of heat (such as sunlight), doors and windows airflow or external wall temperature.

3. Pre-embedded electrical cartridge, to choose the standard 86-cartridge, it is recommended that the cassette depth of 50mm. Special attention to Europe and the United States thermostat of 86 cassette, the dimensions do not match, be confirmed before embedded. Keep the the cassette cavity clean, remove the decoration left over debris.

4. External sensor (to probe) installed to be embedded casing, to ensure that the installation, maintenance plug. Casing at the ground should be sealed to prevent moisture and debris from entering.

5. Do not install the thermostat in the bathroom, sauna, steam room (high humidity or may splash walls), such cases the thermostat must be mounted on the outside by using a longer probe, in order to control ground temperature.

6. Water heating system thermostat can provide a synchronization (or programmable) passive linkage interface, you can achieve linkage control of the boiler, pump and valve control.

7. Electric heating system with thermostat the total load should not be greater than 3500W (current is less than 16A). Particular attention to the load cable and a terminal connection must be reliable.

8. According to the the electricity load power to set aside sufficient current cable.

9. Floor heating system power supply, be sure to install separate electrical circuit with safety shut-off, leakage protection.

10. Due to the wall cassette space constraints, initial installation thermostat you might encounter many problems such as: the space is small, difficult to trace, press inequality. Please be patient, carefully review the instructions, follow the correct steps, or consult the manufacturers.

Mechanical thermostat

Using sensitive gas diaphragm or thermal bimetal temperature sensing element, a mechanical contact thermostat switch. This type of thermostat is more, only a small part of the domestic manufacturers to promote such products in the U.S. and European markets. The mechanical floor heating thermostat usually contact current is not greater than 8A, control valves for water heating system on and off. The advantages of low cost, simple to install and use, and long-term reliability; deviation of the temperature control switch generally greater than ± 3 ° C), the display is not intuitive, single function; output contact current only 8A, also limited the in electric heating engineering.
