APPENDIX A. WHAT’S NEW WITH THE P125 CONTROL BOARD

A.ADVANTAGES OF THE P125 CONTROL BOARD

1.Temperature displays in Fahrenheit or Celsius.

2.Improved troubleshooting by status display of:

a.Actual Supply and Return Temperatures

b.Flame Signal

c.Fan Speed

3.Service Mode allows installers to manually control the firing rate for easy set up.

4.Available Software that allows the installer to access status information and fault history from a PC.

5.Optional Interface Module that allows the boiler to be operated with a 0-10 volt analog input signal from a modulating controller (such as Tekmar 265, 263, and BTC MPA) for features such as:

a.Outdoor Reset Control.

b.Dual temperature set points for space heating and indirect hot water demands.

c.Modulating Sequencing for up to three boilers.

The Pavilion 410 is an external control that allows the boiler to be controlled with a 0-5 volt analog input signal. An interface module is not necessary. The Pavilion 410 provides features a. and b. (above).
