ngExample with Heat Offset at 40% flow

Cooling 0V - 4.5V Heating 5.5V - 10V

Frese OPTIMIZER controls both heating and cooling with only one single data point from the BMS system, through a 0 -10V external control signal (1).

Full modulation is provided with even different design flow of heating and cooling.

The design flow rate for the cooling system defines the maximum flow through the coil and is set using the Pressure Independent 2 way Control Valve, Frese OPTIMA Compact. Frese OPTIMIZER Controller offers setting of hot water flow, from 100% down to 10% of the maximum flow. The Heat Offset flow can be set using the dial on the Frese OPTIMIZER Controller (2) - each dot indicates 10% of maximum flow.

The switch over from cooling to heating is automatically changed via the signal from the BMS data point. Frese OPTIMA Compact Pressure Independent Control Valve is closed during the switch over and remains closed for approx. 12 minutes until switching of the 3-way valves has been safely completed. The switch over condition is signaled by the flashing of the Off-LED lamp (3).F
