The MP2is capable of controlling the supply water tempera- ture for up to nine ON / OFF stages based on outdoor tem- perature, control for the Domestic Hot Water (DHW) gener- ation, a set point requirement or optionally an external input signal (0 - 10 V (dc)). A large easy to read display provides current system temperatures and operating status (FIG. 1). The control has outputs for a primary pump and a combus- tion air damper or alarm. Based on the mode of operation selected, the control can operate different combinations of boiler stages and boiler pumps.
