About Advanced HVAC CONTROLLER (AHC) Advanced HVAC CONTROLLER (hereafter referred to as AHC) comprises of MITSUBISHI ELECTRIC’s AHC ADAPTER (PAC-IF01AHC-J) and α2 SIMPLE APPLICATION CONTROLLER* (hereafter referred to as ALPHA2). * ‌ α2 SIMPLE APPLICATION CONTROLLER is one of the Programming Logic Controllers that are manufactured by MITSUBISHI ELECTRIC CORPORATION.

1. Safety precautions ●● Thoroughly read the following safety precautions prior to installation. ●● Observe these precautions carefully to ensure safety. WARNING Indicates a risk of death or serious injury. CAUTION Indicates a risk of injury or structural damage.
PAGE 4
To reduce the risk of injury or electric shock, before spraying a chemical around AHC, stop the operation and cover AHC. To reduce the risk of electric shock, malfunctions, smoke or fire, do not operate the switches/buttons or touch other electrical parts with wet hands. To reduce the risk of injury or electric shock, stop the operation and switch off the power supply before cleaning, maintaining, or inspecting AHC. Properly install all required covers to keep moisture and dust out of AHC.
PAGE 5
CAUTION To reduce the risk of shorting, current leakage, electric shock, malfunctions, smoke, or fire, do not install AHC in a place exposed to water or in a condensing environment. AHC must be installed by qualified personnel according to the instructions detailed in this manual. Improper installation may result in electric shock or fire. Precautions during wiring WARNING To reduce the risk of damage to AHC, malfunctions, smoke, or fire, do not connect the power cable to the signal terminal block.
PAGE 6
CAUTION To reduce the risk of electric shock, shorting, or malfunctions, keep wire pieces and sheath shavings out of the terminal block. To reduce the risk of electric shock, malfunctions, or fire, seal the gap between the cable access holes with putty. To reduce the risk of shorting, current leakage, electric shock, or malfunctions, keep the cables out of contact with the AHC edges. Precautions for moving or repairing AHC WARNING CAUTION AHC should be repaired or moved only by qualified personnel.
PAGE 7
To reduce the risk of erroneous signal output, malfunctions, and resultant accidents, provide an external safety circuit to ensure a safe operation of the entire system in case problems occur with external power supply or with AHC. To avoid malfunctions, do not bundle power cables and signal cables together, or place them in the same metallic conduit. To reduce the risk of electric shock, turn off the power to AHC before installing or wiring AHC.
PAGE 8
Do not turn off the power to AHC or reset AHC while making the settings. Doing so will corrupt the settings data on the Flash ROM and require re-setting of data. It may also result in malfunctions. When controlling heaters or pumps with AHC, a large current (10 times the normal current) may pass through these units when the output signal turns from OFF to ON. Select units that can tolerate such current flow.
PAGE 9
2. Important notice • Read this manual before installing or using AHC, and follow all the instructions. • This manual contains explanations and figures to help the user to properly install, program, and operate AHC. • All the examples and figures contained in this manual are there for the sole purpose of clarification. It is not guaranteed that AHC will properly work in the types of applications used as examples or are shown in figures.
PAGE 10
3. Functions AHC comprises of an ALPHA2 and an AHC ADAPTER. The use of AHC ADAPTER requires the use of ALPHA2. The following ALPHA2 are compatible with AHC. Other types of ALPHA2 do not support AHC.
