Note:
1. When the hydrobox is powered via outdoor unit, the maximum grand total current of (a)+(b) is 3.0 A.
2. Do not connect multiple water circulation pumps directly to output (OUT1, OUT2). In such a case, connect them via (a) relay(s).
3. Do not connect water circulation pumps to both TBO.1 1-2 and CNP1 at the same time.
4. Stranded wire should be processed with insulation-covered bar terminal (DIN46228-4 standard compatible type).
5. Use the same thing as the Signal input wire for OUTA1 wiring.
5.3 Indoor unit only operation (during installation work)
In the case when heating operation is required prior to connection of the outdoor unit; i.e. during installation work, an electric heater in indoor unit (*1) can be used.
*1 Model with electric heater only.
1. To start operation
● Check if the indoor unit power supply is OFF, and turn DIP switch 4-4 and 4-5 ON.
● Turn ON the indoor unit power supply.
2. To end operation *2
● Turn OFF the indoor unit power supply.
● Turn DIP switch 4-4 and 4-5 OFF.
*2 When the indoor unit only operation is ended, ensure to check over the settings after outdoor unit is connected.
Note:
Prolonged running of the this operation may affect the life of the electric heater.
