OUTPUTS
VALVE ACTUATOR
The Genesis Heat-Timer
®
is designed to connect to a motorized valve actuator. Using the inputs from the outdoor temperature
sensor and the system temperature sensor, the Genesis Heat-Timer
®
controls the heating system by opening and closing the
motorized valve actuator. The valve can be either a 2-way valve for a steam to water exchanger application or a 3-way mixing valve
for a low temp radiant application or a 2-way valve for a district steam heating application.
For valve actuators requiring a proportional/modulating signal, the Genesis Heat-Timer
®
can provide a current voltage signal. In this
configuration the Genesis Heat-Timer
®
controls the heating system by modulating the valve from 0% to 100%.
BOILER BURNER
The Genesis Heat-Timer
®
is designed to connect to the boiler burner. Using the inputs from the outdoor temperature sensor and the
system temperature sensor, the Genesis Heat-Timer
®
controls the heating system by turning the boiler burner ON or OFF.
BURNER MODULATION
The Genesis Heat-Timer
®
is designed to provide the boiler burner in a hot water application, a current voltage modulation signal.
Using the inputs from the outdoor temperature sensor and the system temperature sensor, the Genesis Heat-Timer
®
controls the
heating system by modulating the boiler burner from 0% to 100%.
SYSTEM PUMP—
HYDRONIC
The System Pump output relay will energize when the outdoor temperature drops below the Outdoor start or whenever the boiler
output is active.
SYSTEM PUMP
(OUTPUT)
—
STEAM
The system output relay connects to and operates a combustion air-damper or other boiler room equipment and it will energize
whenever there is a call for the boiler.
MODEM
The Genesis Heat-Timer
®
is designed to reset the communication modem. In the event Internet communication has been lost for
more than a hour, the Genesis Heat-Timer
®
will reset the modem power connection by opening the relay contact.
