1. Pump continuously and fan through the water valve connection of the OC.
This is the most cost-effective option. The pressure of the OptiClimate must be adjusted manually by means of a control valve periodically depending on the outside air temperature. This option can be used for all capacities but will most often be chosen for the smaller capacities.

2. Pump and fan through Pump/Fan controller.
The Pump/Fan controller automatically controls the fan speed and only starts the pump when it is needed. The advantage of this fully automatic system compared to system 1 is a lower power consumption, a quieter system and no manual adjustment required. A set contains: • Pump/Fan controller • Fan/Pump Box • Temperature sensor (10m) • Start sensor (10m). Per OptiClimate is one start sensor required, order one additional sensor if two OC’s are used.

3. Pump and fan through double inverter controller.
This system controls the fan and the pump through 2 inverters. The advantage over system 2 is a much lower power consumption and an even quieter system. The set contains: • Pump/Fan controller • 2x frequency controllers (inverters) • 2x temperature sensor (10m) • Start sensor (10m), order one additional sensor if two OC’s are used.
