Commercial Programmable Thermostat 4H/2C
The Venstar T4800 is a commercial-grade digital thermostat designed for multi-stage HVAC systems. It supports up to four heating stages and two cooling stages, making it suitable for gas/electric or heat pump configurations. Installers can select 7-day, 4+1+1 day or single-day programming with up to three occupied periods per day. The unit requires a common power wire for operation.
WiFi Module and Display Features
The included ACC-VWF1 WiFi module adds remote connectivity to the thermostat. Its scrolling display simplifies initial setup and can be customised to show a dealer name, phone number and alert messages. Adjustable backlight intensity and colour-coded buttons with legends improve visibility and ease of use in varied lighting conditions. The interface supports auto-changeover, heat-only or cool-only modes.
Multi-Stage Capacity and Limits
Four heating and two cooling stages provide capacity for larger commercial zones with staged equipment. The three occupied periods per day handle typical business schedules but may not cover complex multi-shift patterns. Programming flexibility is limited to the three predefined schedule formats. Systems requiring more than four heating stages, two cooling stages or additional schedule types fall outside this thermostat's capabilities.

Questions about this item
What maintenance will the T4800 thermostat need over time?
Replace the backup batteries periodically to keep programming intact during power outages. Clean the display and buttons with a soft dry cloth when dust builds up.
What limit appears first when the thermostat runs continuously in a commercial space?
The four heating and two cooling stage outputs set the maximum number of equipment steps the thermostat can sequence before it can no longer add capacity.
How much heat or noise does the unit produce when powered all day?
The thermostat itself draws very little power and runs silently; any audible click comes from the HVAC relays it controls, not from the thermostat.
