iDM Heating & Cooling

Use cases

• Run the heat pump at reduced mode during expensive grid hours and boost during cheap hours, using dynamic tariff data piped into an automation.
• Alert the installer when the heat pump error code becomes non-zero, with the error number included in the notification for faster diagnosis.
• Chart flow and return temperatures side by side to detect a failing circulation pump or clogged heat exchanger.
• Log cumulative thermal energy for heating, cooling, and hot water separately for SPF or seasonal COP reporting.
• Remotely raise hot water target temperature before the customer returns from holiday, without having to send them to the controller panel.

Installation

1. 1Activate Modbus TCP on the Navigator Control 2.0. Instructions are iDM specific and available only to iDM partners, so contact the local partner if the service menu is locked.
2. 2Connect the Navigator controller to the local LAN. On some iDM models the LAN port is directly on the heat pump housing; on others it is in the control cabinet.
3. 3Note the Navigator IP address and set a DHCP reservation.
4. 4In ModbusCloud, add a Modbus TCP device at the Navigator IP, port 502, slave ID 1.
5. 5Import the iDM Heating and Cooling template. Temperatures should start updating within the first polling interval.
