Sunamp Thermino hp-VT wiring – Thermino hp-VT
Important: Please follow (Table 1) for information regarding the Links
.
Table 1: Wiring Thermino hp-VT – Link 1 & 2 settings
Link 3 will be provided fixed within the product; for this product type it
MUST remain in place. Removing the Link 3 will result in increased consumption
and running times of the Vaillant Arotherm Plus Heat Pump.
- Run and connect 3 Core mains power supply cable (16A minimum, minimum 2.5mm? CA) from the Double-pole isolating switch to the Heat Battery controller (Figures 2 and 3).
- Wire the cable via the appliance case grommets and into the control box housing (Thermino hp installation manual Figure 8 and Figures 2 and 3 below).
- Prepare if necessary and wire the mains power cable in the following terminals (Thermino hp installation manual, Figure 10 and Figures 2 and 3 below):
- Brown (Live): Terminal L1 (Live)
- Blue (Neutral): Terminal N1 (Neutral)
- Green/Yellow (Earth): Terminal PE (Protective Earth)
Electric override switch wiring
Wire a 2 core shielded PVC insulated cable (minimum 0.75mm? CSA, 24 x 0.2mm
according to BS 6500) from a 2-pole Volt-free contact switch, run the wire
into the appliance via the appliance case cabling grommets and then into the
control box housing through the hole available. Secure the cables in Terminal
T1 & T2 independently (Figure 2 & Figure 3).
Warning: Please DO NOT connect a fused spur for this connection.
Note: This switch should be off by default. Engaging this switch will put
the Heat Battery into electric charging mode only and disable the function of
the Vaillant Arotherm Plus Heat Pump until the switch is set to off. This can
lead to increased electricity consumption, resulting in higher energy costs.
This should be explained to the end user and the switch labelled accordingly.
External heat source sensor cable wiring
Wire a 2 core PVC insulated cable (minimum 0.75mm? CSA, 24 x 0.2mm according
to BS 6500), the heat battery controller in this application acts as hot water
thermostat. The cable will act as a hot water heating tank sensor from the
heat battery controller terminals T3 & T4 into the Vaillant Heat Pump
Interface controller SP1 screw terminals 1&2 (please refer to Vaillant
Arotherm Plus Installation manual. Please run the wire into the heat battery
appliance via the appliance case cabling grommets and then into the control
box housing through the hole available. Secure the cables in Terminals T3 & T4
independently (Figure 2).

- Run and connect 4 Core mains power supply cable (16A, minimum 2.5mm? CA) from the Solar Power Diverter to the Heat Battery. (Thermino iPV installation manual, Section 3.9 and Figures 5 and 6 below).
- Wire the cable via the appliance case grommets and into the control box housing (Thermino iPV installation manual, Figure 8 and Figures 5 and 6 below).
- Prepare if necessary and wire the mains power cable in the following terminals (Thermino iPV installation manual, Figure 10 and Figure 5 and o below):
- Brown (Live): Terminal L1 (Permanent Live)
- Black (Live): Terminal L2 (Modulating Live)
- Blue/ Grey (Neutral): Terminal N1 (Neutral)
