is 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.
