Smart T-Stat installation: Low Voltage output on Burnham MPO IQ Boiler Control
I am a DIY'er with little experience with boilers attempting to install an ecobee 3 thermostat before the winter and am running into some difficulty. It appears the voltage output on the control system (see page 9 of wiring manual in the link below) is low with direct terminal readings on my multi-meter for Rh-W (Left-T and Right T in schematic) of 14 volts and Rh-C (C wire is Terminal 3 in schematic) of 2 volts. The output for Terminal 2 and 3 leading to the Indirect Water Heater read 24 volts. My meter readings are directly from the terminals not from the t-stat wires in the wall. According to the schematic in the link below, it is a 24 volt system, does anyone have any advice as to why the voltage output from my boiler is below 24 volts. The multi-meter readings with the indirect water heater disconnected are the same as above.
I very much appreciate any help with this issues in advance.https://www.thermoflo.com/wp-content...e+-+MPO-IQ.pdf
