SPWK 800 FLOATING THERMOSTAT

SUNGO SPWK 800 floating thermostats are suitable for heating, ventilating, and air-conditioning system (HVAC). When TS series temperature sensor detects that ambient load is changed, the thermostat sends an output signal to adjust actuator by proportional and integral arithmetic

FEATURE

.Inside temperature sensor adopt NTC heating resistance
.Wire with outside temperature sensor can come up to 50 meters.
.One scale cage that can be locked is needed in thermostat in case of unprofessional workers changing setpoint.
.Proportional belt can be modulated.
.Output function shift: Direct or converse (summer/winter)
.Spare setpoint
.Flexible mount: Mounted on wall, embed in wall, mounted hidden in fan coil or mounted on terminal device

POWER DRIVE DOLLOP

Matched with various of LCD thermostat .
Relay with 7A 250VA output ,which can bear
 heavy loading and with high reliability.
Smart bulk make installation easier.
Wrong connecting way, big current on touch point or unstable voltage can not be easy to make the instrument destroyed.
Comparing with another drive way:
Controllable silicon drive:
a) High damage-rate because ofwrong
 connecting way or unstable voltage.
b)Higher damage-rate with 3A relay than 7A relay
