Flow Balancing
1. Adjusting the Balancing Knob, or
2. Adjusting the dial located under the Adjustment Cap. Dial is adjusted with the use of the Adjustment Key. The key comes attached to the manifold via nylon tie.
Flow can be visually fine-tuned by viewing the sight glass indicator while adjusting the balancing valve on the return manifold.
On-Off Circuit Control
For systems requiring individual circuit thermostatic control, an electronic Valve Actuator is installed. Valve Actuators are four-wire, to connect to the zone thermostat and use end switch wires to activate the circulator. With this arrangement, every room can be thermostatically controlled from one central distribution manifold.
Note:
1. Stainless Steel Manifolds can be used to control fan coils or baseboard units, as well as floor heating.
2. Manifolds are not intended to exceed 87 psi at 194?F operating conditions
