Grant QR Range User Manual

Section 5: Electrical Page 19
Figure 5-3: Grant QR integrated indirect heat pump cylinder connected to a Grant Aerona³ ASHP, as part of a S-Plan plus type system
with UFH (Grant UH8 Wiring Centre) and a radiator circuit
The control system shown in this diagram shows the “hot water priority” switch on the EP001 wiring centre in the left hand
‘ON’ position. This ensures that the ASHP cannot operate to provide space heating and hot water at the same time.
For information regarding the operation of the Greenbrook T205-C timer shown in this control system wiring diagram, please
refer to Appendix B at the back of these installation instructions.
