Introduction The PYROBOX3/3C/5-TRACE power boxes together with the PYROTRACE controller and interface panel, offer smart and easy control for HEAT TRACING SYSTEMS. It can operate up to 4 heating zones and one auxiliary zone, with selectable sequencing method. Typical applications include pipes, valves and gutters. The backlit LCD screen provides full interface and information to the system status.
PYROBOX Series Installation PLEASE READ THIS MANUAL AND THE SAFETY WARNINGS CAREFULLY BEFORE INSTALLING AND USING THE CONTROLLER AND SAVE IT FOR FUTURE USE Installation notes Familiarize yourself with the markings, warnings, components and terminology. The PYROBOX power boxes and its accessories must be installed by a qualified electrician in accordance with local regulations and the requirements of the NEC (NFPA 72 ) and the CEC part 1.
Aquastat PYROULS 50 AMP max. per pole 30 AMP max. supply (option) (By Meitav-tec) 120 VAC Heater load connection Important! If the heaters are connected in star, the neutral must pass through the internal current transformer ring and the external branch circuit protection.
Wiring the PYROBOX3-TRACE Heater load connection Provide contactors C1, C2, C3 and C4 with up to 300 VAC, 30 AMP. Make sure the wire Gauge (AWG) is suitable for the circuit Amperage draw, as specified in the NEC/ CEC table 1.
Operating instructions Turning the system ON and OFF Press and hold the [ON] button for 0.5 seconds to turn the system ON or OFF. The words “ON” or “OFF” will appear on display. Selecting temperature scale Press the [+] button for Celsius. Press the [-] button for Fahrenheit.
Technician settings Use the technician settings mode to view and adjust the following parameters: Temperature set point Enable/Disable 2 temperature sensor Lower ambient temperature limit to stop logic (Aquastat) heaters Heaters outputs logic Time delay before stopping the heaters MODBUS MAC Address for home ON time for manual mode automation system (option) Heaters cycle time / Splitting time...
Technician settings (Cont’) P02 - Lower limit temperature for heating Press the [SELECT] and [+] buttons simultaneously. “P02” and the low limit temperature will appear on display. When the temperature on the temperature sensor drops below the low temperature limit, the heating system will stop. Use the [+] and [-] buttons to adjust the temperature set point.
Technician settings (Cont’) P04 - Manual mode ON time Press the [SELECT] and [+] buttons simultaneously. “P04”, “On” and the time “Manual ON” mode time period will appear on display. The hours will blink. The delay time parameter defines a time frame in which the heaters remain ON after receiving an “Manual ON”...
Technician settings (Cont’) P07 - Heaters outputs logic (by TEMPERATURE SENSOR or by AQUASTAT SENSOR) Press the [SELECT] and [+] buttons simultaneously. “P07” and the figures “0”, “1”, “2” or “3” will appear on display. Use the [+] and [-] buttons to define the logic of output 1-5 as follows: Temperature Sensor Aquastat Sensor Option...
Technician settings (Cont’) P09 - Test conditions mode / Technician commissioning mode Turn ON test conditions to check the functionality of the system regardless of temperature sensors parameters (i.e. during the summer). In test conditions, the Ambient temperature is always -7°C/19°F. Press the [SELECT] and [+] buttons simultaneously.
Technician settings (Cont’) DIP switch S2 - Short measuring times (test only) Use DIP switch S2 to short the - “ON” - Short measuring times – for test/commissioning only (measuring times will be divided to 60). - “OFF” - Normal operation. Short measuring times: A real 1 hour will take 1 minute and a real 1 minute will take 1 second.
Technician settings (Cont’) Enable/Disable zones Follow the steps below to enable or disable each of the 5 zones. By default, all zones are enabled. 1. Turn the thermostat OFF. 2. Press and hold both the [+] and the [-] buttons simultaneously for 10 seconds. 3.
System Errors Error 1 – MODBUS Communication error “SensErr 1” Will appear on display.
