Siemens Building Technology 188-0030 Thermostat Refrigerant ensuring optimal refrigerant flow andThe Siemens 188 0030 is a heavy duty unit mounted pneumatic thermostat designed specifically for high low temperature control in HVAC terminal units like fan coils and induction units. This TH 188 HC model features a direct acting (DA) heating and reverse acting (RA) cooling sequence, making it a critical component for two pipe changeover systems. Engineered with a bimaterial sensing element, it provides reliable proportional control and pneumatic
