Verdant VX3-TW-W-LIT Wireless Thermostat
Introduction
- Easy-to-use Thermostat
- Unparalleled Energy Savings
- Aux output for occupancy-based control of external devices (i.e. lights, receptacles, outside air dampers)
- Facilitates compliance with energy efficiency codes such as Title 24, and IECC 2015/2018.
- Online management capabilities¹
The Verdant VX3-TW-W-LIT thermostat delivers unprecedented energy savings without compromising guest comfort.
New energy-efficient building codes have raised the energy performance standards required of commercial buildings.
California’s Title 24 (Part 6) building code as well as other state building codes founded upon IECC 2015 or 2018 energy efficiency codes have now mandated occupancy-based control of heating and air-conditioning, lighting, outside air dampers, and/or receptacles.
The Verdant VX3-TW-W-LIT thermostat reduces HVAC runtime by dynamically setting back temperature in empty rooms, without disturbing the comfort of occupants.
The thermostat can also power a lighting circuit by using an external relay that receives the thermostat’s occupied/unoccupied signal.
The occupancy-based thermostat solution includes a dry contact switch on port J9 of the HVAC controller (see diagram on next page) that closes when occupancy is detected by the onboard sensor or any other remote wireless occupancy sensor.
When occupancy is detected, the dry contact J9 (activated by positioning a jumper in port J10) will close and allow a 24VAC transformer to energize the coil of an external relay R1 installed to control the lighting circuit.
In the absence of occupancy detection, after a configurable amount of time, the J9 switch will open and interrupt the flow of power to the lighting relay.
The Verdant thermostat and Verdant HVAC Controller communicate wirelessly for a simple and effortless installation. The Verdant HVAC Controller connects to the HVAC unit using a standard wire harness.
In the case of a mini split or VRF unit, please contact Verdant Sales for the applicable part number.
Verdant’s combined solution offers building owners a cost-effective energy management system that can be deployed with minimal accessories, and little to no extra labor, making it simple to install.
The VX3-TW-W-LIT thermostat facilitates building-code compliance by addressing the following requirements:2†
