RCD Type B protection specified
Any SmartRTC Room thermostats connected to the system can be powered from a Switched Fused connection unit supplying 230v and each SmartRTC needs a Modbus comms cable (shielded twisted pair cable ie Belden 9842 or equivalent) connecting the SmartRTC terminals "A, B & GND" back to the indoor heat pump controller. If multiple SmartRTC room thermostats are installed, the Modbus comms cable must be "daisy chained" from one SmartRTC to the next before connecting to the indoor heat pump controller. A "star" network is not permitted.
Finally, the local Distribution Service Operator (was previously called DNO) must be informed of every heat pump installation. so that they can better plan any network upgrades that may be required in the future:
Connecting electric vehicles and heat pumps to the networks – Energy Networks Association (ENA)
