12. Error
The icon indicates there is malfunction.

11.4 MAIN LOGICS

11.4.1 Water temperature difference for compressor starting

Parameter 1 "water temp. difference TS6" is used to control the compressor on or off.
When down tank temperature T2 is lower than setting temperature TS1-TS6, the compressor will work to heat the water until
reaching the setting temperature TS1. On the display the top part temperature T3 of the water tank is always visualized.

11.4.2 External pump

T2: lower tank temperature
T3: upper tank temperature
Checks to be done to use the external pump:
• parameter 14 has been configured;
• the optional probe T6 has been electrically and hydraulically connected;
• the external flow switch (optional) has been electrically and hydraulically connected;
• an external pump (not provided) has been electrically and hydraulically connected.
When used for sanitary hot water circulation, the pump will start when the below conditions are satisfied at the same time:
1. Wired controller is ON;
2. T3 ≥ parameter 15+parameter 16;
3. T6 ≤ parameter 15-5°C
The pump will stop when one of the below conditions is satisfied:
1. Wired controller is OFF;
2. T3 ≤ parameter 15-2°C;
3. T6 ≥ parameter 15
When used for solar water circulation, the pump will start when the below conditions are satisfied at the same time:
1. Wired controller is ON;
2. T6 ≥ T2+parameter 17
3. T2 ≤ 78°C
The pump will stop when one of the below conditions is satisfied:
1. Wired controller is OFF;
2. T6 ≤ T2+parameter 18
3. T2 ≥ 83°C
Pump anti-block function: when the pump stops for 12 hours, it will be forced to run for 2 min.

11.4.3 Flow switch

After the pump is running for 30 sec, if the water flow switch signal is checked to OFF for 5 sec, the pump stops. The pump will
restart after 3 min. If this malfunction occurs 3 times in 30 min, the pump can not start until the unit is re-powered. The relating
error code will be shown on the controller. Only the pump will be stopped but not the unit itself.
