INJECTION PUMP MIXING CONTROL
The system 3000 injection Pump Mixing Control with reset
provides control of the water temperature in the secondary
(radiant) loop of a heating system, based on outdoor air
temperature and design temperature settings using an injection
pump. It also provides protection against boiler condensation
by monitoring and controlling the return water temperature.
VALVE MIXING CONTROL
The System 3600 3-way Mixing Valve Control with reset provides
control of the water temperature in the secondary (radiant) loop of
a heating system. The system applies accurate proportional control
to 3-way or 4-way mixing valves based on indoor/outdoor reset
temperatures. It also provides protection against boiler condensation
by monitoring and controlling the return water temperature.
