Mechanical thermostat, electronic thermostat, temperature controller with one week programming, wireless week programming thermostat, wired OT-type thermostat, wireless OT-type thermostat and the resulting derived multi-channel temperature Control and so on.

 

Now in accordance with the different types of thermostats were introduced different types of thermostat for the same use of energy-saving effect.

 

Mechanical indoor thermostat: the oldest indoor thermostat, the use of bimetal to control the temperature, no battery or external power supply. But the disadvantages are obvious, the temperature control accuracy is poor, the temperature control switch precision control is relatively poor, the control of the boiler is a switch control, that is, through the indoor thermostat switch to the indoor thermostat command , There is no communication between the two.

 

Electronic thermostat: electronic thermostat with a temperature sensor to sense the indoor temperature, more accurate temperature, for indoor temperature control fluctuations than the mechanical thermostat small, and between the boiler is also through an indoor temperature Control switch to control, the boiler for the thermostat instructions is a passive response.

 

With weeks programming thermostat: wireless week programming thermostat is a kind of electronic thermostat, to meet the diverse needs of customers.

OT is the short name of Open Therm, which is a communication between the HVAC (heating and cooling equipment) and room thermostat is not limited to the manufacturer's control system communication name, which consists of communication protocol and port specifications, Represents an advanced technology system that uses high-functionality and future expansion possibilities using a simple, simple installation method.

 

OT has now developed into a communication standard for boiler and indoor thermostat, from the initial OT-protocol to the current OT +, the members of the association are mainly composed of European manufacturers of wall-hung boilers and indoor thermostat manufacturers.

 

OT is connected through a unique communication between the wall-mounted furnace and indoor thermostat, you can access from the indoor thermostat and set all the parameters of the boiler, and the indoor temperature and the operation of the boiler linked, The goal is to control the indoor temperature and the size of the boiler flame, so that the indoor temperature as much as possible to maintain the target temperature, and to maintain the temperature of the constant, unlike the traditional indoor thermostat and the boiler is only one Switch control, the indoor temperature of the long delay, the use of indoor temperature will be a great fluctuation.

 

Analysis of Energy Saving Experiment of OT Thermostat Compared with Common Type Thermostat

OT-type thermostat will be more energy-efficient than the use of traditional thermostat, the following is a Danish Danish company to do a test experiment.

Experimental environment: 3 exactly the same European 3 bedroom, the external ambient temperature of 10 ℃

EXPERIMENTAL STANDARD: Three different boiler controllers were controlled using three different temperature controllers to achieve room temperature and set the target temperature to 20 ° C

Test results: mechanical controller (18.7-21.4 ℃ fluctuation 2.7 ℃)
