The HUHAA-PRO Series Unit Heaters bundles the popular HUHAA unit heater with the most commonly-ordered accessories. Bundled options include our most popular safety and control accessories designed to make heating your space effortless and ordering a breeze. 

The HUHAA PRO series delivered standard with:

  • A disconnect switch for safe and easy maintenance or repair
  • A 24VAC transformer for easy integration with a low voltage thermostat today or in the the future
  • A built in single stage thermostat for easy operation and control out of the box

PRO+ Models come standard with:

  • The SmartSeries® Plus thermostat and B10 bracket for a superior out of the box installation experience
  • The SmartSeries Plus control offers optimal control and easy integration whether via a BACnet MT/TP BMS or its standalone digital, 7-day programmable touchscreen with cooling and vacation modes comes standard with no extra components

Bundled Benefits:

  • Increase Availability: The PRO Series heater is a stock unit and therefore there is no longer a wait for the same configured features of yesterday!
  • Better Pricing: Enjoy the benefits of the three added accessories without the full cost of a similar configured style unit.
  • Safety: The disconnect switch gives peace of mind to the maintenance worker because the disconnect switch will cutoff incoming power to the unit so it can be easily repaired. The low voltage transformer no longer requires you to work with line voltage control for easy and safer control.
  • Simple Setup + Integration: All of the accessories come factory installed and therefore the unit is ready to wire and mount once it reaches your door.
  • Easily Stocked: This PRO Series bundle reduces the number of skus to stock and therefore is easily stocked and readily available on the shelves of distributors nationwide.
