Temperature/water level switch | 230 VAC | °F.
SERIES TSWB DIGITAL TEMPERATURE/WATER LEVEL SWITCH
Two Temperature Set Points, Low Water Level Alarm
The Series TSWB Digital Temperature/Water Level Switch has a high and a low set point for controlling the water temperature. The low set point can either be manually or automatically reset. This control also has a conductivity probe input. This input supplies 12 VAC to the conductivity probe to check for low water condition. There are three relay outputs which can be assigned in the field to the high temperature set point, low temperature set point or the low water level input. The Model TS2-K configuration key can make configuring multiple controls quick and easy.
Product Applications
- Wood or pellet boilers
- 3 outputs for high temp, low temp or input alarm
- Conductivity probe input for water level monitoring
