The AH2430 is an actuator that can be used on applications such as heating / cooling
circuits. The AH2430 has two sensors which are connected between the self-balancing
actuator and the fluid supply and return, or inlet and outlet of the manifold. The self-
balancing actuator will measure the temperature sensors and adjust the actuator to
maintain a differential temperature of 14°F (7°C).

CALIBRATION (This procedure may take up to 30 minutes)
It is critical that the AHR240 be calibrated once properly installed on the manifold as the pin length of valves from
different manufacturers will vary. Do not tighten or loosen the AH2430 collar during or after calibration. There
must be a constant flow of water through the supply manifold and the water temperature be maintained at a
constant 86°F (20°C) or higher throughout the calibration process.

Auto Balancing Actuators
• Apply power to the AH2430 and wait at least 20 seconds, but not more than 60 seconds, then remove power.
• When power is next applied, the LED on the AH2430 will flash for 2 minutes before starting to stroke the valve.
• The AH2430 will stroke the valve to its fully open position and then to fully closed.
• Next, the AH2430 actuator will open the valve in small increments, every 2 minutes, until heated water is detected in the
supply pipe. This is called the valve open point (VOP).
• Once the VOP is determined, the valve will fully open one more time to establish the range of motion.
IMPORTANT NOTE: Once the above calibration is complete, DO NOT tighten or loosen the AH2430 collar or
re-calibration will be required.
• Connect the brown/blue wires to a switched 24V (AC or DC) supply.
• Install the AH2340 on the manifold, ensuring that it is fully tightened. Once installed, DO NOT tighten or loosen.
• If a balancing valve is installed, ensure that it is fully open.
• Install the pipe temperature sensors facing forward on the supply and return pipes 4” (10 cm) downstream of the manifold.
NORMAL OPERATION
• Once calibrated the AH2430, when powered, will flash the LED for two minutes before fully opening the valve.
• The AH2430 will modulate the valve between VOP and fully open depending on the on the required temperature difference.
When the zone thermostat is satisfied, the AH2430 will close the valve completely until the next call for heat.
