Smart Heat Pump iQ Inver Silence, Full Inverter Technology

Use cases

• Monitor inlet and outlet water temperatures on a live cloud dashboard to verify heat pump performance remotely.
• Create an alert when a fault code is reported so you can respond before the pool owner notices a problem.
• Schedule power on and off commands to prevent the heat pump from running during expensive electricity tariff periods.
• Log compressor speed percentage over time to detect efficiency degradation or undersized equipment.
• Adjust heating mode temperature setpoints remotely when seasonal conditions change without a site visit.
• Track defrost cycles to identify potential airflow obstructions or low refrigerant charge early.

Installation

1. 1Obtain the special Modbus connection cable with 4-pole plug required by the Aquastar Air heat pump.
2. 2Wire the Modbus RTU connection cable from the heat pump to the RS485 terminal on your ModbusCloud gateway (MCG or MLP series), connecting A, B, and GND correctly.
3. 3Set the Modbus RTU baud rate to 9600 on the gateway to match the heat pump default configuration.
4. 4Confirm the Modbus slave address configured on the heat pump and enter the same address in the ModbusCloud gateway settings.
5. 5Import the Smart Heat Pump iQ Inver Silence template from the ModbusCloud template library and assign it to the correct gateway port.
6. 6Verify communication by checking that inlet water temperature and compressor speed values appear on the ModbusCloud dashboard.

Things to watch for

01

The gateway cannot communicate with the heat pump. What should I check first?

Verify that you are using the correct special Modbus connection cable with the 4-pole plug. Standard two-wire RS485 cables will not fit the heat pump connector. Also confirm that A, B, and GND are wired to the matching terminals on the gateway.

02

What baud rate does the heat pump use?

The default baud rate is 9600. Make sure the ModbusCloud gateway port is also configured to 9600 baud, 8 data bits, no parity, and 1 stop bit (8N1) unless the heat pump documentation specifies otherwise.

03

What are the E, P, and F registers in the template?

These registers map to internal configuration parameters and fault codes of the heat pump. E registers typically represent operational parameters, P registers cover protection or configuration settings, and F registers hold fault history. Refer to the Peraqua Aquastar Air Modbus documentation for detailed descriptions.

04

Can I control cooling mode temperature setpoints through this template?

The current template exposes control of temperature setpoints for automatic and heating modes. Cooling mode setpoint control is read-only in this template version. Check for template updates in the ModbusCloud library if additional write registers become available.
