The ESBE series GRC200 are circulation units designed for heating circuits where control by weather or indoor/outdoor temperature and pump control is required. Equipped with two shut-off valves with thermometers, check valve, high class insulation shell and high efficiency circulation pump with PWM control signal.
The circulation unit series GRC200 is delivered with a 3-way rotary progressive mixing valve which ensures the best regulation performance independent of flow rate and low risk of oversizing. It is also delivered with a weather compensating controller (GRC220) or combined indoor/outdoor temperature controller (GRC240). The built-in pump control allows for pump control in 8 different ways.
The circulation units series GRC200 are available in DN25 and DN32 with either a Wilo or Grundfos pump.

Pump control – ESBE Circulation unit GRC200
Operation
Installation example
The heating circuits A & C are equipped with GRC240 and the heating circuit B is equipped with GRC220.
The GRC240 units are controlling the heating circuits according to the heating curve and the indoor temperature, as well as controlling the pump according to ∆t with pump on/off function.
The GRC220 unit is controlling the heating circuit according to the heating curve and controlling the pump according to ∆t with pump on/off function.
The benefits of using the circulation units series GRC200 in this application are:
● High indoor temperature comfort thanks to ESBE Smart Control and Self-Adaptive System
● Controlling the ∆t, return temperature to the heat pump to maximize the COP (Coefficient of Performance) and system performance
● Controlling the pump on/on for energy savings in case when heat is not required.
