  • Page 19: Operating Concepts

    2.0 Operating concepts This section contains important information about the control strategies used in the controller to deliver space heating, domestic hot water (DHW), pool heating, garage heating, and snow-melting. Depending on heating requirements, strategies will include the use of these control modes: DHW, Reset Heating, Setpoint, Ext.

  • Page 20: Reset Heating

    When applied to IBC's condensing boilers, the Reset Heating mode enables efficiency benefits by lowering the required circulating water temperature, so that cooler water returns to the boiler (promoting more condensation).

IBC's controller offers two reset heating methods for controlling the supply/outlet water temperature: 1. "Standard" reset heating (default) that uses a two-point reset heating ratio.

Design Supply ° – the desired boiler outlet temperature to occur on the coldest day. Use this temperature when performing heat loss calculations.

  • Page 25: External Control

    2.4 External Control The controller's reset mode adjusts the circulating water temperature to maintain a steady and comfortable indoor temperature. Indoor temperature is compared with the preset operating range (set point target), and if the temperature deviates (as sensed by the room thermostat), the controller will bring the temperature back to the set point limits.

  • Page 26: Zone Of

    Syncing zones with "Zone Of" on page 2.6 Setting load priority Boiler load is the total "work" performed by a boiler. IBC's controller uses a priority algorithm to coordinate or schedule the delivery of heat in multiple load systems. This type of planning strategy temporarily turns off one or more loads based on given conditions in the system.

This is a percent of the maximum firing rate of the lead boiler – on a 40-399 G3, for instance, a value of 60 would correspond to an output of 399 x 60/100 = 239.
