Introduction

The PYROBOX3/3C/5/19/19 power boxes together with the PYROCON12/19 controller and interface

panel, offer smart and easy control over the PYRO Snow & Ice Melting system.

It can operate up to 4 snow melting zones and one auxiliary zone, with selectable sequencing method.

Typical applications include driveways, sidewalks, loading docks, stairs, pavements and gutters.

The backlit LCD screen provides full interface and information of the system status.

The use of several zones staggering allow covering larger area for snow melting with a limited available

electrical power.

The PYROBOX/19 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 - Adjustable snow sensor sensitivity

- Optional auxiliary control based 3rd party - Commissioning/Test environment

snow sensor (e.g. Gutter/Pavement sensor) - Master/Slave connections

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 (GFEP)

The ground fault interrupter/residual current detector installed in this system is a Non class A

GFEP, 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 GFEP 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

Roof side installation

The PYROSENSE aerial sensors are supplied with:

1. A plastic cap, to protect the sensor from dust and debris for when the sensor

is not in use (off season).

Important! The protective cap must be removed before use of the sensor.

If the protective cap is not removed, the sensor will not detect snow!

2. Plastic spikes, to be used if necessary, to keep birds off the sensor.
