Room Thermostat
1. Product Summary:
S400 series of digital thermostats adopt PI and intelligent prediction controlling ways, which not only can avoid the overshoot and imbalance of environment temperature at the setting values, but also can avoid the frequent movements caused by the adjustments of device. S400 series of digital thermostats are usually applied to control 2 -pipe & 3-speed fan coil and motorized valves, or control 4-pipe&3-speed fan coil and motorized valves in the business, industrial and civil constructions.
