I have a Tekmar House Control 400 with a Tekmar TN2 Wiring Center 313 attached to the expansion terminal so that together they control the boiler, indirect DHW, and 8 hydronic heating zones. Currently there is one Tekmar Outdoor Sensor 070 connected to the House Control 400 "Out/Com" sensor terminal and it is working fine (outdoor temperature displays on all the termostats, etc). I see that the Wiring Center 313 also has an "Out/Com" terminal for connecting to an Outdoor Sensor 070. Can I connect a second Outdoor Sensor 070 to that empty terminal on the Wiring Center 313 and have two outdoor sensors on my Tekmar system (e.g. a sensor on the north side and a sensor on the south side of my house) and be able to view the temperature of either/both? Note that I also have a Tekmar Gateway 485 connected to this system for remote monitoring/control.

I had these guys install a new hot water boiler. I had a hole in one of the baseboard heater pipes. The guys said they would return the next the day to fix the pipe and finish the job. They never returned that was a few months ago. I had the pipes repaired and fired up the boiler. It comes on I can hear the circulating pump working. I hear the electronic iginitor clicking for about 30 seconds and then it stops and the boiler doesn't light. This is a Green Mountain boiler model GMGWB070FE. This boiler is new and as far as I know has never been on. Any input would be appreciated. I just got a new camera and learning how to use it. I will post some pictures soon if needed.
