Description
The EFCB Series Networkable Fan Coil Controller and TFL
Series LCD Thermostat are designed for simple and
accurate control of any fan coil application. The Networkable
Fan Coil Controller is mounted inside the fan coil cabinet and
incorporates a configurable fan coil algorithm, variable three
speed fan control and either modulating or digital heating
and cooling outputs. All inputs and high/low voltage outputs
are centralized at the control module in the fan coil cabinet.
