| Overview

VAV with Reheat- No Fan) is a terminal profile that uses a SmartNode to control a terminal VAV box. The profile supports both the cooling and heating requirement for a zone.

Based on the system-level equipment, AHU or RTU is in cooling mode or Heating mode the damper and reheat operations enabled provide the optimum results for the zone based on the zone load.

The VAV with Reheat- No Fan allows the choice of dampers, reheat based on the equipment used, and the zone priority which equates to the importance multiplier in guideline 36.

On the heating side, the profile supports both the staged & modulating reheat controls.

| Sequence of Operation

The sequence of operation is completely driven based on Occupancy mode, Space Current Temperature, the set Cooling and Heating Desired Temperatures, CFM, and Space CO2 levels.

Let us understand the Sequence of operations based on the occupancy modes, and how the other factors contribute to the sequence of operations during different types of occupancy modes.

| Occupancy Modes

The occupancy mode (Occupied or Unoccupied) shall be determined through a user-adjustable, graphical, seven-day schedule with a holiday schedule, alongside the configurable autoaway and forced occupied options (external schedule influencers) for optimized controls and enhanced energy savings.

Based on the above aspects, factoring in the occupancy the following can be the possible applicable occupancy modes:

  • Pre- Conditioning
  • Occupied
  • Unoccupied
  • Auto-Away
  • Forced Occupied

| Sequence of Operation During Pre-Conditioning

Pre-conditioning is a state just before the building enters the scheduled occupancy. It starts at more like the unoccupied state, the desired temperatures drift to unoccupied setbacks.

The preconditioning uses an algorithm to start the conditioning before the building is scheduled for occupancy, from the heating side or cooling side, to bring the building to an optimum level ( within the occupied heating & cooling desired temperatures) exactly at the time of occupancy start.

A cooling and heating coolingPreconditioningRate and heatingPreconditiningRate tuners defaulted to 15 minutes, are used alongside the occupied heating/cooling desired temperature breach to determine when the pre-conditioning should start.

Example Calculation:`

When,

  • The heating & cooling desired temperatures are 70F and 74F for the building,
  • The current temperature is 76F (Average of zone temperatures),
  • 8:00 AM is the time the building is scheduled to be occupied.

Then the preconditioning start time is calculated as follows:

Cooling Desired Temperature Breach= 76-74=2F

Preconditioning duration= coolingPreconditioningRate (mins) * Cooling Desired Temperature Breach

                                        = 15*2

                                        = 30 mins

The preconditioning starts 30 minutes before the building is scheduled to be occupied, which is = 7:30 AM.

The zones would operate as shown below to accommodate the preconditioning from the system equipment.

During Warm-up:

  • If the space temperature is below the occupied heating desired temperature, the space utilizes the warm-up via HeatingLoopOutput as below.
