How It Works



Comfy's sophisticated solution is non-intrusive and integrates seamlessly with your existing systems. Users request and receive real comfort and control. Comfy is not a placebo! Comfy works great in open spaces, and also helps reduce, not increase ‘temperature battles.’ Comfy works with direct digital control systems of many varieties, including VAV, CAV, FCU, UFAD, VRF, Heat Pumps and more.

Steps from Installation to Use

1. Comfy requires no major hardware upgrades. The Comfy Gateway plugs into your BMS network, and requires an outbound internet connection.

2. Users make a request to warm or cool their space via the app. This request is sent to the Comfy Cloud. Users do NOT have access to directly change the temperature.

3. The Comfy Gateway reads the request from the cloud, and translates it into a BACnet command to temporarily adjust the setpoint.

BMS and Controls Compatibility

Comfy is compatible with most major BMS vendors. Systems must be BACnet enabled (yes, we are BTL certified) and have the necessary points available for Comfy to read/write (these vary by system type). We use a variety of sequences to produce two key outcomes: Immediate comfort and Comfy Learning. Comfy sequences will always meet the needs of the specific system in place and control vendor, and these commands are only sent to terminal units, not to base building plants. All control sequences are agreed upon with the customer in advance of launch.

Requests in Detail

The immediate response is an adjustment to the temperature setpoint, which then typically releases after 10 minutes. Over time Comfy aggregates what it has ‘learned’ from the requests and automatically adjusts setpoints (within an agreed upon range) to better match user preferences. Comfy will widen temperature deadbands (to the agreed upon limit) in underutilized spaces and/or where there are no requests. This machine learning response is what helps our customers save energy.
