When set temperature, the first control valve of control is opened, until when room temperature is greater than or equal to third preset temperature value, control the
One control valve is closed.And can also be when temperature is greater than or equal to set temperature indoors, the second control valve of control is opened, until room
When interior temperature is less than or equal to the first preset temperature value, the second control valve of control is closed.It is set in this way, room temperature is less than or equal to
Determine temperature and show there are heating needs, controls the unlatching of the first control valve at this time, so that the hot water in water pipe provides heat for interior, and
Temperature is greater than or equal to third preset temperature indoors, i.e. when T+1, the first control valve of control is closed, and avoids winter Indoor Temperature

Demand controls the unlatching of the second control valve at this time, so that the fresh air in air hose provides cooling capacity for interior, and temperature is reduced to indoors
When the first preset temperature value, i.e. T-1, the second control valve of control is closed, and avoids the too low problem of winter room temperature.It is alternative
Traditional 2 control air-conditioning system of 4 control or subregion, the room of Lai Shixian different periods in winter or when conditioning in Transition Season is to room temperature
Requirement it is different, to reduce the operating cost of air-conditioning.
Correspondingly, the blast velocity control of fan coil when present mode of operation is heating mode are as follows: if currently running mould
Formula is heating mode, then when temperature is less than or equal to the first preset temperature value indoors, the air rate adjustment of fan coil is supreme
Limit value；When temperature is greater than the first preset temperature value and is less than set temperature indoors, by the air rate adjustment of fan coil to first
Setting value；When temperature is greater than or equal to set temperature indoors, by the air rate adjustment of fan coil to the second setting value.
It, can temperature indoors under the mode it should be noted that present mode of operation can also include orderly heating mode
Less than or equal to set temperature value, when such as 5 DEG C, the first control valve of control is opened, and heat is provided for interior, until room temperature reaches
When to 10 DEG C, the first control valve of control is closed, and is always maintained at the closing of the second control valve, so that night or festivals or holidays room in winter
Between nobody when, room temperature will not be subcooled, can effectively it is antifreeze.
