Abstract
A fan coil controller for a hot and cold water system of a building that turns off the fan while the hot water and cold water coils are flushed. A fan coil control circuit is configured to periodically and temporarily operate a hot water flow control circuit and a cold water flow control circuit to cause a flushing of the hot and cold water system and simultaneously provide a signal to a fan control circuit to prevent the thermostat enabling the fan during flushing of the hot and cold water system.
Claims2
A fan coil controller for a hot and cold water system of a building, the fan coil controller comprising:
- a hot water flow control circuit;
- a cold water flow control circuit;
- a thermostat, the thermostat being connected to a power supply;
- a fan coil control circuit incorporating a timer, a first relay on the hot water flow control circuit and a second relay on the cold water flow control circuit;
- the first relay being controlled by the timer to control electrical power supplied to the hot water flow control circuit and to control a connection between the hot water control circuit and the thermostat;
- the second relay being controlled by the timer to control electrical power supplied to the cold water flow control circuit and to control a connection between the cold water control circuit and the thermostat;
- and
- the fan coil control circuit being configured to periodically and temporarily operate the hot water flow control circuit and the cold water flow control circuit to cause a flushing of the hot and cold water system while simultaneously disconnecting the hot water control circuit and the cold water control circuit from the thermostat during flushing.
