● double metal diaphragm box temperature sensing element is required to ensure accurate temperature control. 
 ● beautiful and chic styling make the perfect thermostat is installed in the indoor environment, particularly suitable for use in the office of office space and rooms of hotels and restaurants. 
 ● all models, thermostats with heat premonition heat premonition can be further improved hot and cold temperature control. 
 ● The thermostat can be mounted directly on wall or junction box. 
 ● The toggle switch can be manually controlled system operation and fan speed. 
 Hot and cold automatic conversion of some models by the pipe thermostat control (thermostat) 
 ● Special features: A gauge stop B security cover C for special installation needs Wall 
 ● temperature sensing element 
 The thermostat's temperature sensing element is welded together by two edge of circular elastic metal diaphragm. 
 The pressure of internal sealed gas / liquid two-phase mixture with the ambient temperature changes cause expansion and contraction of the diaphragm box, driven by a contact switch to control the heating or cooling loop. 
 ● heat premonition 
 Under normal circumstances, the heat premonition always in the heating and cooling to maintain the connection.
