The HERO 8 Way Contactor + Heater is a device designed to control the timing of lighting and heating systems, primarily for horticultural applications. It acts as both a clock and a segmental timer, allowing users to program specific ON/OFF periods for connected appliances.

Function Description:

The primary function of the HERO 8 Way Contactor + Heater is to switch electrical loads for High Intensity Discharge (HID) lighting systems and heaters. It features an 8-way contactor, meaning it can control up to eight individual lighting systems. The integrated heater control allows for a separate set of appliances to be managed. The unit operates based on a 24-hour timer, which can be programmed to automate the switching of these systems.

Important Technical Specifications:

  • Lighting Sockets: The unit is capable of controlling:
    • 8 x 600W HPS (High Pressure Sodium) lighting systems.
    • Alternatively, 4 x 1000W HPS lighting systems.
    • Note: It is explicitly stated that the unit is not recommended for use with LED lighting due to the in-rush of current on start-up, which can cause issues.
  • Heater Sockets: The total load for the heater sockets should not exceed 2500W.
  • Power Cords: The unit has two power cords, each designed to carry up to 13A. The left-hand power cord is designated as the 'master' and supplies power to the timer and contactor, meaning it must be plugged in for the unit to function.
  • Electrical Load Balancing: For safety and optimal performance, the total current required by all lighting systems on either side of the unit should not exceed 13A. Any load applied to the unit should be evenly distributed across both sides. For example, if connecting 4 lights, 2 should be plugged into one side and 2 into the opposite side.
  • Circuit Breakers: The unit is equipped with two circuit breakers. The left circuit breaker is connected to the sockets on the left-hand side and the heater sockets. The right circuit breaker is connected to the sockets on the right-hand side. These breakers trip to cut power if the unit is overloaded.
  • Fuse: The main fuse in the plugs should be a 13amp fuse.

Usage Features:

  • Installation: The unit comes with four pre-installed brackets for wall mounting. Users are instructed to fit a fixing through the hole in the bracket and secure it to the mounting surface.
  • Initial Set-Up:
    • Before connecting any lighting or heaters, the timer must be set up, and the unit must be connected to power.
    • Access to the timer is gained by opening its covers.
    • The timer switch has three positions:
      • '0' position: Lighting sockets OFF / Heater sockets ON.
      • '1' position: Lighting sockets ON / Heater sockets OFF.
      • Middle (timer) position (clock symbol): Both Lighting & Heater sockets will switch ON / OFF based on the programmed timer settings.
  • Setting the Current Time (Clock Function):
    • The inner part of the timer acts as the clock.
    • To set the current time, the grey centre pin should be turned clockwise to move the minute hand. The segmental timer around the clock should be disregarded during this step.
    • The timer is a 24-hour clock. Numbers 3, 6, and 9 on the inner dial indicate AM, while 15, 18, and 21 indicate PM.
  • Setting Program Times (Segmental Timer):
    • The outer part of the timer consists of segments.
    • To program 'ON' periods, these segments should be pushed inwards towards the centre of the clock. Segments that are pushed in will activate the connected sockets (ON), while segments that are not pushed in will keep them OFF.
  • Turning the Unit ON:
    • To activate the timer function, the switch must be in the middle (timer) position.
    • Users can verify the unit's operation by temporarily moving the switch to '1' (lights ON) and then '0' (heaters ON) to check power to the respective systems. After verification, the switch should be returned to the middle position.
  • Safety First:
    • Always disconnect the unit from the power supply before set-up or maintenance.
    • Ensure the unit remains in a dry area and is not accessible to unfamiliar individuals.
    • Avoid plugging the unit into extensions or adaptors, as the high current can pose a fire risk.
    • After switching the unit off, wait at least 5 minutes before unplugging to allow connected appliances to safely discharge.

Maintenance Features:

  • Resetting the Circuit Breaker:
    • If a circuit breaker trips (indicated by a loss of power to a bank of 4 sockets or heater sockets), disconnect all lights and/or heaters from the affected bank.
    • Reset the breaker by pushing the switch to the up position.
    • To identify the problematic appliance, reconnect each light individually with the timer switch in position '1'. If the breaker trips again, that light is either overloaded or faulty.
    • For heater issues, turn the timer switch to '0' and reconnect heaters individually. If the breaker trips, the heater is overloading the circuit or has an electrical problem.
    • Once issues are resolved, return the switch to the middle (timer) position.
  • Troubleshooting:
    • If a specific socket fails, test it by plugging in a known working appliance. If it still fails, the unit should be returned to the retailer.
    • If the unit has no power to any sockets or to one side, check if the circuit breakers have tripped and, if necessary, change the main fuse in the plugs.
    • To replace a fuse, remove the plug, prise out the fuse carrier with a small screwdriver, replace with a 13amp fuse, and push it back in.
    • Persistent tripping of circuit breakers indicates that the connected load is too large for the unit.
  • Warranty: The unit carries a 2-year warranty (terms and conditions apply).
  • User Serviceability: There are no user-serviceable parts inside the unit. Tampering with the unit will void the warranty. The manufacturer is not liable for damage caused by the operation of the unit.
