Heatmiser Plus User Manual Configuring the system The Heatmiser Plus is our multipurpose control and has a wide number of configurations available. This section aims to guide you through the configuration process. To configure the Heatmiser Plus follow the steps below;... - Page 13 Note: If compensation or boiler sequencing is required on the system these must be setup before any optimised zones. The Heatmiser Plus has 9 relays which can be used for various applications depending on the configuration selected. To calculate the number of relays required for your system observe the following table.
- Page 14 Configuring the system (Continued) Sensor Averaging… The Heatmiser Plus has the facility to average two temperature readings. For example you may have a large heating zone which would be controlled better if two temperature sensors were Installed in the zone and the average reading taken. To set this up follow the steps below;...
