6 Podcasts About Fan Coil Thermostats
6 Podcasts About Fan Coil Thermostats
First, let's view a picture as below, and think,"are they the same"?
Obviously, totally they are different, even though they look almost the same from the appearance.
So it is with the Fan Coil Thermostats suppliers.
As a professional thermostat manufacturer, Hotowell always develop its products close to market's needs, and today we are discussing 6 Podcasts About Hotowell Fan Coil Thermostats.
1.℃ or ℉ temp. unit displaying
In some specific market like US, the ℉ is more often visible in unit displaying, while in other markets, ℃ seems more common. Hotowell combines these 2 units in products, e.g.Star level Fan Coil Thermostat model HTW-31-F17, by long pressing M button for 5s to switch between ℃ or ℉.
2.Fan Mode Select
Factory default set it as 3-speed fan output, high-medium-low-auto, but in some hotel application like in Hotel lounge area, the lounge fan doesn't need 3 speed, just on/off and 1 valve on/off is enough. e.g. Fan-coil speed(1 speed or 3speeds) configurable in ISU process in parameter 2 in Hotel Noise-Free fan coil thermostat.
3.Installation type（2piles/4pipes）configurable
Under normal circumstances, 2-pipe(tube) thermostats or 4-pipe thermostats won't be made integrately. But considering the standard market needs, it is better to combine these 2 installation types together, and configurable in ISU, Hotowell thermostat HTW-31-F17-2K2N make in this way.
4. Dead band configurable
The dead band configurable is to avoid the thermostat frenquantly switch on/off and aim to an energy saving purpose.
This function is a must.
If the difference between heating and cooling set points is less than the dead band set in ISU, then the dead band set in ISU is enforced. When adjusting the cooling set point, conflicts will be resolved by moving the heating set point out of the way of the cooling set point (heating set point=cooling set point –dead band set in ISU).
When adjusting the heating setpoint, conflicts will be resolved by moving the cooling set point out of the way of the heating set point (cooling set point=heating set point +dead band set in ISU).
Heating and Cooling range stops will determine the maximum heating setpoint setting and minimum
cooling setpoint setting.
5.Key-Card 2 NO/NC type Select
It is not sure that the door/window card megnetic contact is NO or NC, with this selectable, it feeds better with different occupancy system.
6.Modbus Communication Protocol
Generally speaking, the Modbus communication based on the wire RS485 connection is not difficult.
but many thermostat suppliers do not make it as standard, they just make with their own company standard.
Resulting in the thermostats can be connected by the Modbus devices.
For Example, in Modbus Thermostat HTW-31-F13：
On commander code： id 06 9c 40 00 55 CRC1 CRC2
Off commander code： id 06 9c 40 00 aa CRC1 CRC2
Read Temp. commander code： id 03 9c 46 00 01 CRC1 CRC2
Write Set Temp. commander code： id 06 9c 49 TH TL CRC1 CRC2
Reading All Date commander code: id 03 9c 40 00 08 CRC1 CRC2
Write All Date commander code: id 10 9c 40 00 08 10 DAT1_H DATI_L…DAT8_H
DAT8_L…CRC1 CRC2.
