HERCULES®Low Voltage Contact Module
REASON TO USE A LOW VOLTAGE CONTACT MODULE:
This module is designed to interface any “120V output” to Air Conditioning/Heating “Low Voltage Control Inputs.”
Some Titan Controls®Controllers have “120V outputs” (eg. Apollo®series timer, Zephyr®series controllers, Eos®series controllers,
Atlas®series controllers … ). Should you need to control any SYSTEM whose inputs are not compatible with 120V output power,
you must use this module and refer to the connection diagram in the USER GUIDE of the SYSTEM you want to control.
ELECTRICAL SPECIFICATIONS:
Input: Low Power Coil - 120V AC 60HZ 0.4W
Output: Low Power Contact - 5A at 24V DC / 120V AC MAX.

LOW VOLTAGE CONTROL INPUTS ON TYPICAL HEATING OR COOLING SYSTEM:
When using the Hercules®
, power lines to the SYSTEM, it must be connected directly to the building electrical box. Control inputs are
