Dekamatik-HK1 control

222063748

Can anybody explain to me how the Dekamatik-HK1 control works. I have one that is flashing the outdoor temp. every second to different temp. I just want to inform the HO how this system works with just an outdoor sensor.

Sheesh

that could take awhile,, maybe Perry could take a stab at this?
I`m sure he`ll diagnose to death, the problems of having this control in the first place(if any), LOL!

Dekamatik-HK1

Hi Shawn:

My system has a Dekamatik-HK1.


The control has an outdoor sensor and a boiler supply
water sensor. Using a sophisticated program and a
microprocessor, it controls a motorized valve that
mixes water from the boiler with water returning from
the house to supply hot water to the radiators in the house. As the outdoor temperature gets colder, it
uses more boiler water to provide hotter water to the
radiators in the house. How hot that water is is
determined by the program set up by the installer or
the homeowner. The program has dozens of options and
adjustments available, much more than I could tell you
about here. Your best bet is to obtain a manual from
Viessmann.


I was unable to find "a blinking, variable outdoor
temperature" indication in the troubleshooting sections
of my manuals. My guess would be that there is a problem
with the wiring to the outdoor sensor.

This heating system has about 12 high temp zones and run all of taco sr controls and then it has a seperate dekamatic control just for the radiant system. It connects to a 4 ay mixing valve. I just didnt know if they are known to have a blown board or something but i will check the outdoor sensor.

Self-diagnostics

The HK-1 has self-diagnostics and will tell you what's wrong. You'll need the manuals which can be downloaded from the Viessmann website.
