When you think of large open spaces, garages, or shops you typically think of big doors and unit heaters. When you think of server rooms and kitchens in the south, you probably think of AC units. 75F offers a way to easily integrate these devices using a Smart Node.
I walked into an auto body shop once that had only 6 unit heaters. 2 of which were not functional and nobody knew about it. What they did know, is that come winter, they got cold. Whether it was my presence or top of mind, the employees wanted to tell me about it. With a 75F integration for this application we were able to tie the unit heaters for the shop and the RTUs for the office to a single login where the managers finally felt they had the power to do more than make a phone call. They now had some recourse for employee comfort complaints.
That example was in a fairly small shop. But imagine a 400,000sq.ft. warehouse with 50 unit heaters lining the perimeter. No visibility. They will work as long as they work and when they break, go unnoticed until enough of them go out that the building starts performing so poorly that something must be done. The repairs should and can be preventative.
A Smart Node controlling a single stage piece of equipment is really very simple. The Smart Node has two dry contact closures [click here to see the Smart Node Overview] that can be used to control 1 fan and 1 piece of heating or cooling equipment based on temperature.
With the ability to set heating and cooling dead bands, as well as their associated hysteresis values you can increase runtime and efficiency of the units themselves.
The temperature value for a SSE zone can be read using one of the 75F available sensor options or using any old 10k Type II sensor that may already be available.
- Remote Temperature and Humidity (RTH) Sensor. Perfect when being installed in drywall or other framed walls.
- Flush Mount Temperature and Humidity (FTH) Sensor - Perfect for installing on beams where the sensor wire must be exposed and can not be hidden.
- Ceiling Mount Temperature and Humidity (CTH) Sensor - Great for when the available wall space is limited or if in a space with a lot of solar gain.
- Any 10k Type II - No more limitations to what kind of sensor you can install.
In Floor Heat Control
In floor heat systems are typically pretty simple. You turn on a pump and open a valve. Using a Smart Node configured as SSE with a 10K Type II slab sensor is a perfect match for most in floor heating applications.
Exhaust Fans and MAU
I mentioned that one of the relays can be used to control a fan. If all you need is something to run a fan on a schedule and perhaps monitor the current consumption as a status indicator. The SSE profile is a wonderful solution.
