Operation:
Hot water is controlled using the Samsung cylinder sensor and controller supplied.
This controller has inbuilt time clock control and includes both a daily and weekly
legionella sterilisation function.
The system can be either open vented or pressurised.
The cylinder must have a coil at least 2.5m^2
Cylinder size normally allows 55l of water per person per day.
We would recommend sizing the heat pump to recover the cylinder in 1 hour.
It is possible to connect this system to solar PV powered immersion heaters (I boost,
Immersun etc.)
Heating is controlled using a wall mounted thermostat / time clock (field supplied).
There are no limits to the number of heating zones which can be connected to this
system. This system shows 2 heating zones. (Pump 2 and Pump 3)
Each zone has its own thermostat / timer which drives a dedicated zone valve. The
zone valve will control the pump and send a run signal to the heat pump.
The system will run in a fully adjustable weather compensated mode adjusting the
water temperature to suit the ambient conditions.
We recommend a buffer; low loss header or heat exchanger is used to simplify the
installation.
