TTM Shuntopac® 125-200 VÅ
Constant flow in exhaust air heat exchanger circuit.
Variable flow in supply air heat exchanger circuit.
The control valve is installed as a mixing valve.
1. Connect differential pressure instrument to adjustment valve with measuring point.
2. Set the control valve to fully open position (stem depressed, bypass closed).
3. Measure the water until it reaches the calculated value.
4. Set the control valve to fully closed position (stem up, bypass open).
5. Adjust the inner adjustment valve until the outer adjustment valve achieves the same pressure drop as before.
