Abstract
A valve controller for a hot water heating system having a water heating device, a water circulating device, and heater device. The Controller operates a water control valve between an open and a closed position, the valve controller comprising, a flow timer for variably establishing flow periodicity between a minimum flow time and a maximum flow time, a base cycle timer for variably establishing base cycle periodicity between a minimum base time and a maximum flow time. The base timer variably establishes a base cycle periodicity between a minimum base time and a maximum base time. A selector responsive to heat requirements for select a flow time and base cycle time.
Claims17
A valve controller for a hot water heating system having water heating means, water circulating means, and heater means by operating a water control valve between an open and a closed position, said valve controller comprising:
- flow timer means for variably establishing flow periodicity between a minimum flow time and a maximum flow time;
- base cycle timer means for variably establishing base cycle periodicity between a minimum base time and a maximum base time;
- and,
- selector means responsive to heat requirement for selecting flow time and base cycle time.
A valve controller for a hot water heating system in a building having a determined heat loss characteristic and a heating system therefor including water heater means, water circulating means, and heater means for supplying variable amounts of heat thereto, said water circulating means including a water control valve, said valve controller comprising in combination:
- first environmental condition sensing means for sensing the outdoor temperature, said means providing a first derived control signal in response thereto;
- controller means for controlling the flow of heated circulating water in response to the monitored first environmental condition, said first valve controller means, in turn, comprising:
- flow timer means for variably establishing flow periodicity between a minimum flow time and a maximum flow time;
- base cycle timer means for variably establishing base cycle periodicity between a minimum base time and a maximum base time;
- and,
- selector means responsive to heat requirement for selecting flow time and base cycle time;
- and,
- a valve operator means for operating, in response to said valve controller, said water control valve between an open position and a closed position.
