Thermostatic Fan Control, 2-Pipe System with Safety Cycle Ð This control is used for high humidity situations in which condensate problems can occur if fan is turned off while chilled water is still running through the coil.

The wiring provides fan cycling from HIGH to LOW on the cooling cycle and from LOW to OFF on the heating cycle. An ON-OFF toggle switch replaces the standard 3-speed fan switch. The toggle switch can be concealed to ensure that the unit runs on low speed when cooling. This action greatly reduces the chance of condensation problems that exist with other standard fan cycling controls.

Thermostatic Electric Valve Control, 2-Pipe Ð

A thermostatically controlled 2-position valve provides su- perior control to fan cycling. With this control, the fan runs continuously unless it is manually switched to the OFF po- sition. The fan must be on before the valve can be opened to supply water to the coil.

This system can be used for normal 2-pipe changeover systems and can also be furnished for cooling-only or heating- only applications by omitting the changeover and specifying which application is intended.
