Viessmann Trimatik-mc issue

Member Posts: 1
I have a viessmann trimatik-mc installed in 1999. so far so good... I installed sensors to investigate the usage of 9 zones from a supply and return standpoint. After a couple of days I investigated the graphs. I noticed that two 1 hour times during the day the main supply dropped the temperature. I believe the Trimatic-mc is telling the supply to reduce the temperature. I reset the system and set the clock. I am still seeing the one hour drops. In trying to setup the Weekday and time selection I am not seeing the time displayed on the lcd display. I do not remember if this is to be displayed. The manual does not show this. Does anyone know about this? Thx...

Time to climb into the "way back machine."
It has been a while since I worked on a Trimatik. I will dig for my manuals and post later.0 -
Bad Clock
Change the timer and the cube. They are the only 2 parts still available for the Trimatik.
They do make a retrofit kit to put the new controls on the boiler. The timer and Cube are not cheap....There was an error rendering this rich post.
