P825 Control Board

Every Peerless Pinnacle boiler is equipped with a P825 Control Board that offers state-of-the-art technology, including outdoor reset control with an additional outdoor temperature sensor. The P825 also has built-in technology for domestic hot water priority when an optional indirect tank sensor is added. With this feature, the temperature setpoint and differential temperature of the domestic hot water can be regulated through the boiler control. The P825 control board’s LED digital display module lets users view supply and return temperatures, flame signal and fan speed (firing rate) for enhanced boiler serviceability. A switch to "service mode" enables contractors to manually control the firing rate. An optional interface module allows for modulating sequencing of multiple boilers and the capability of interfacing with building energy management systems. Also available for the P825 is PC software to display boiler status and fault history.
