Tekmar 265 & Pinnacle Boiler

Put online today. We have a few small glitches to work out. This is an 8,000 sqft house. The 4,000 sqft basement has 6 zones. All zones are radiant floor heat, slab-on-grade. The Main level is 4,000 sqft gypcrete overpour that is also radiant floor heat with 6 zones.
The tape over some of the globe valves and circs indicate zones we haven't brought on-line yet.

Matt is the installing contractor, he is no-longer a "diamond in the rough", he is pretty well polished in radiant floor heat. (I was just the system designersales guy).

The Pinnacle 199 low fires at 66,000 btu's, some of the smaller zones are only 2-3000 btu's, that is why the buffer tank. I also like the soft-stop, DHW purge functions going to the buffer tank before the zone heating resumes after the DHW takes priority and then satisfies.

The "265 Mechanical" pic is the design that Matt installed around. This was a great residential job that took a little planning. The general contractor is very detail oriented. We had a half-hour discussion about which type of electrical conduit would look best. (It's Thomas & Betts liquitite).

Anyway, thought you might enjoy some pics. I think the hydronic bug has biten Matt and he might be a "wall-flower"
this evening. He is deserving of many kudo's I think.

    Very nice, BUT......

    Shouldn't you have put on a TACO jacket? Not a B&G pump in sight. ;)

    Interface Module

    I have been getting questions on the Interface Module. This is made for Peerless. It is a model 91488.

    The tekmar 265 (and 263) want to modulate from a 4-20ma signal, the pinnacle only puts out 0-10V DC, the interface module take the 0-10DC and converts it to 4-20ma.

    The Pink and Light Blue lead snap into the printed circuit board of the boiler(The Molex connector on the circuit board), the purple and yellow tie into terminals 6&7 on the 265 control.

    Hello Paul,

    Is the Interface card for the Pinnacle readily available to everyone or is still hard to obtain? I realize the interface is new for Peerless.

    Didn't seem to be a problem

    The new pinnacle has the updated PC125 board right out of the factory and that is the only way they are shipping right now.

    I have the interface module in stock. It took about 3-weeks lead time to get. I haven't heard of any problems about production or inability to ship.
