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.
The Use of several zones staggering allow covering longer pipes length with less available electrical
power.
The PYROTRACE offers various operating and programming options such as:
- Switchable temperature scales (°F or °C) - Adjustable Lower ambient temperature limit to stop
- Both Automatic and Manual modes heaters (lockout)
- Adjustable heaters cycle and splitting times - Energy saving temperature limit
- Adjustable heaters hold on off delay - Commissioning/Test environment

PYROBOX Series Installation
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.
WARNING: Ensure the power is disconnect from all circuits before mounting the power box and
making any connections. Contact with components carrying hazardous voltage can cause electric
shock and may result in severe personal injury or death.
Installer must ensure the installation of approved disconnect means, for all power supply
circuits feeding this unit.
The power boxes are suitable for indoor wall mount installation only.
Ensure wiring according to the provided schematics using copper conductors only.
Make sure the wire gauge (AWG) is suitable for the circuit amperage draw, as specified in the
NEC/CEC table 1.
Ensure that the main breakers (fuses) are suitable for the heating systems rating (80% load).
Grounding means must comply with local regulations and CEC/NEC.
Ensure that the heating system/de-icing system connected to this unit complies with the UL 499 or
UL 515 & CSA 22.2 # 130.3 standard and is certified / listed by an NRTL.
Ensure that all wiring is rated for the application at 60°C (140°F as per UL 515 CSA 22.2 #130
clause 12 table 12.1.
Ensure that any holes punched for conduit are to compromise the integrity of the enclosure ratings.
Ground fault circuit interrupter (GFCI)
The ground fault interrupter/residual current detector installed in this system is a Non class A GFCI,
intended for equipment protection.
Familiar yourself with its operation and required setting.
At installation and commissioning stage use a calibrated milliamp meter to read and record the
heating systems natural leakage.
Set the GFI/RCD to no more than 30 milliamps higher than that reading.
This step might have to be repeated a few times, to avoid nuisance tripping.
The GFCI should be tested monthly. Please refer to the calibration and testing instructions in
appendix 1 of this manual.
PLEASE READ THIS MANUAL AND THE SAFETY WARNINGS CAREFULLY BEFORE INSTALLING
AND USING THE CONTROLLER AND SAVE IT FOR FUTURE USE
