Installation Instructions

and Operating Manual

The AcuTemp utilizes a microcontroller-based

design to control water temperature. An advanced

software algorithm closely monitors the rate of

tank temperature changes and controls the heating

source to minimize fluctuations in tank temperature

while optimizing fuel efficiency. The control features

adjustable temperature settings for both residential

and commercial temperature operating ranges.

WARNING

All work must be

performed by a

qualiﬁed and licensed professional in accordance with

all applicable codes and ordinances.

WARNING

Electrical shock

hazard. To prevent

electrical shock, death, or equipment damage, discon-

nect power supply before installing or servicing control.

NOTICE - Read these instructions completely before proceeding

with the installation. Retain these instructions for future reference.

SETTING THE CONTROL Push the setting dial to enter the Temperature Setting mode. When pressed, the display will show ‘OFF’ or the current temperature setting. Turn the dial to select the desired water temperature to be maintained in the water heater. See Commercial/Residential (below) for available temperature ranges. The display will return to the operating mode after five seconds of inactivity. IMPORTANT: Temperature variations can exist within the water heater.
