Fast Connect
The fast connect board includes everything that you will need except from the robokit and the cylinder. The fast connect board is a relatively new concept and
was designed to make installers lives much easier. The board is pre-wired and commissioned, the installer just needs to connect the cylinder, heating circuit
and the heat pump flow and returns to the board. There is also some minor electrical work to be undertaken and then everything is ready to go.
The operation of the fast connect board is as normal, the cylinder sensor controls the operation of DHW mode and the external run signal into the MIM
board controls the unit running in heating mode and there are no limits on how many zones are connected. The zones are independently controlled by it’s
own stat or timer of which drives a zone valve. This will control the pump and then send a signal to the unit to operate.
The Samsung heat pump will adjust accordingly in a fully adjustable weather compensation mode and it will adjust the temperature of the water to match the
ambient temperature.
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.
