How TherMOOstat Helps With Cooling Controls

  • by Karen K Dang

King Hall

Intro

In September, we receive 1 chilly and 12 cold votes from Room 1001 in King Hall. The following month we receive another 12 cold votes. The consistent cold votes suggested there may be an issue with the cooling controls to room 1001.

Investigation 1

When we went to investigate, we discovered two issues that caused the uncomfortably cold temperature. The first was that one VAV box was trying to cool the room while a second was trying to heat the room.

We reset the VAV boxes so they would communicate, instead of competing against one another.

 

Investigation 2

The second issue we found was from an old work order that disabled the thermostat.

After we changed the programming to enable the thermostats, we went to the room to manually change the setpoints to 70°F.

Ghausi Hall

Our team began receiving chilly and cold feedback at the end of November from Ghausi Hall.

Intro

Sometimes cold feedback doesn't always indicate an issue. Originally we saw no mechanical failure. However, by the end of January, there were 4 chilly and 9 cold votes for the same room.

 

Investigation

Through our investigations, we discovered a malfunctioning VAV box.

​We submitted our findings to initiate a work order on behalf of the occupants to resolve this issue. TherMOOstat feedback decreased after the work order and we followed up with the occupants via email to verify that comfort improved.
