Air-to-water Heat Pump Split Versati
Notes
(a) Distance between the indoor unit and the remote air temperature sensor should be less than 15m due to
length of the connection cable of remote air temperature sensor;
(b) Height from floor is approximately 1.5m;
(c) Remote air temperature sensor cannot be located where the area may be hidden when door is open;
(d) Remote air temperature sensor cannot be located where external thermal influence may be applied;
(e) Remote air temperature sensor should be installed where space heating is mainly applied;
(f) After the remote air temperature sensor is installed, it should be set to "With" through the wired controller so
as to set the remote air temperature to the control point.
10. Thermostat
Installation of the thermostat is very similar to that of the remote air temperature sensor.
How to Wire Thermostat
(1) Uncover the front cover of indoor unit and open the control box;
(2) Identify the power specification of the thermostat, if it is 220V, find terminal block XT3 as NO.12~15;
(3) If it is the heating/cooling thermostat, please connect wire as per the figure above.
• 220V power supply can be provided to the thermostat by the Versati III heat pump.
• Setting temperature by the thermostat(heating or cooling) should be within the temperature range of the product ;
• For other constrains, please refer to previous pages about the remote air temperature sensor;
• Do not connect external electric loads. Wire 220V AC should be used only for the electric thermostat;
• Never connect external electric loads such as valves, fan coil units, etc. If connected, the mainboard of the unit can be
seriously damaged;
• Installation of the thermostat is very similar to that of the remote air temperature sensor.
