Tekmar controls

Tom_35

I read a post the other night and can't find it now. The install was a really terrific looking job and had Tekmar controls for the radiant heating, hot water, and HVAC. Very nice control system!

Seems like a 363 was used in conjunction with possibly some 150's. Can someone direct me back to the post?

We are starting a job that has 6 ECR direct exchange heat pumps with domestic hot water de-superheaters, radiant heating, pool and spa heating. The domestic hot water will not be on-demand, so we are planning on adding a flat plate heat exchanger from the pool/spa boiler.

We had planned on using the Tekmar 150 for 8 zones and Carrier Thermidistats for the cooling and "back-up" heat. If we can coordinate the controls into a better package, that is the route we want to go.

Haven't decided on which boiler to use yet, but from most of the posts, the Viessman and Buderus seem to be the most popular. Are these brands even available in Arkansas?

Thanks for the info.

I'm in SW Missouri

and have acess to all those brands. Their is a brand new Viessmann rep in Missouri that may be of help.

You should be able to get any of those products within a couple days. Spare parts is the only drawback to hydronics in this area. Keep some of the OEM stuff on the job. Consumables are usually found at Johnstone or Graingers outlets.

Star Wholesale has some branches in Arkansas, they seem the speak beginner hydronics

The tekmar rep for this area is very good, not sure if they go into Arkansas Comfort Sales 618- 656 1655, Kevin Hay.

tekmar control options

Hello Tom,

tekmar's 500 series thermostats with floor sensors can be set to maintain a minimum floor temperature while trying to maintain air temperature. The 512 thermostat can operate heating and cooling.

tekmar also makes boiler staging controls thats can be used to stage heat pumps. The Boiler Control 268 can be used to stage up to 9 heat sources.

If you are unsure of which tekmar control is right for your application, please contact me or anyone in our customer service department if I am unavailable.

tekmar does not have a sales rep in Arkansas. However, the Woodbury-Beach Co. in North Little Rock is a tekmar distributor. Their phone number is 501-753-8323.

Tekmar controls


We have purchased our previous Tekmar controls from Boone & Boone in Tulsa, OK. They are a complete hydronic supplier and carry B&G pumps, Watts products, as well as other materials.

Hot Rod, we have a Star Mechanical Supply in Ft. Smith and have purchased numerous supplies from them.

Jay, I will be in touch with you as soon as we decide on the sequence of operations on the systems.
