MISSISSAUGA, Ont. — Espar Heater Systems has released a pair of new heater controllers: the Multi-Max F1000 and the Digi-Max D1000. The Multi-Max F1000 serves the needs of the Hydronic line of Engine Coolant heaters, while the Digi-Max D1000 serves the needs of the Airtronic D2/D4 bunk heaters.

Multi-Max F1000
Company officials say the Multi-Max gives fleets complete control over their pre-heat coolant heaters, by no longer requiring drivers to program and run their vehicle’s coolant heater.

By introducing a desktop programmer and a Micro SD card slot, the Multi-Max gives “tamper-proof”control of every aspect of every heaters’ operating parameters based on each vehicle’s individual work schedule.

Programming takes less than five minutes, according to officials, with programmable features that include: as many as four distinct events per day, each with a different start and finish time, triggered on whatever day of the week that vehicle is in use; a high temperature disable set point; a maximum manual run-time; a low voltage disable set point; a preferred PM interval; and an exercise scheduler.

Through the Micro SD card slot, those same settings can then be used to program one, or multiple vehicles heaters.

Other features include a tri-colored LED light with a simple flash code notifies drivers when the heater needs either routine or unscheduled attention and one-button on/off control designed for ease of use.

“By taking the driver out of the programming process, running your coolant heaters means no more unnecessary idling, no more needless engine wear-and-tear, no more wasted time, and no more wasted fuel,” officials said in a release. “With the Multi-Max F1000 as soon as your worker’s arrive on site, they’re guaranteed to climb into a warm, de-iced and work-ready vehicle.”

Digi-Max D1000
Officials say the Digi-Max D1000 controller gives drivers maximum control and real-time information. Designers added a larger display screen to accommodate features such as constant heater status display, temperature set point (with either Celsius or Fahrenheit options), and a runtime countdown clock.

The Digi-Max is also designed to help isolate problem shut-offs from routine shut-offs through a “Check Heater” indicator and simplified diagnostic service messages, the company says.

Additional tools and features designed for drivers include easier-to-operate controls through a larger screen and simpler menu, and descriptive fault code messages to help navigate service issues more quickly.

Espar officials say maintenance technicians will also appreciate the depth and quality of information they can access, which helps with quicker and more accurate diagnosis of service issues.

The company says fleet managers will appreciate the complete control the Digi-Max offers, via its maximum run-time limiter, customized PM schedule alerts, and a programmable low-voltage shut-off.
