Product details

Product details:

EM 524 89 and EM 524 90 are universal controllers designed to work with external de-icing systems, building and infrastructure elements.

The only difference between the devices is the ability to control the protected zones:

• EM 524 89 - single-channel 
• EM 524 90 - double channel

Other parameters of both devices are the same.

System control is based on readings of the temperature and humidity parameters.

All definied program parameters are shown on the LCD display.

Entering and changing the settings is carried out by function keys located on the front panel. The model EM 524 90 has two LED indicators to control work

space of two zones.

EM 524 89 has a single channel which can turn on at the same time connected protection system, based on the reading of parameters from one or several independent sensors located at various points of the protected object eg. two gutters on both sides of the roof, gutter and stairs or only on the driveway.

EM 524 90 controller is equipped with a dual-channel structure which in the same way can turn on independently two protected zones such as: roof and stairs, roof and driveway, stairs and driveway, or two sides of the roof, two  parking zones etc.

The controllers can be used to protect:

• roofs
• gutters
• downpipes
• drainage channels
• stairs
• sidewalks
• driveways and
• loading ramps

Wherever the supervision of the de-icing system is necessary to read temperature and humidity.

The controller works with three different types of sensors:

• ESD 524 003 - gutter humidity and temperature sensor
• ESF 524 001, ESF 524 011, ESF 524 002, TFF 524 012 - groundwater humidity and temperature sensors
• TFD 524 004 - air temperature sensor

 in several different variants: 

• 1 x ESD 524 003
• 2 x ESD 524 003
• 1 x ESF 524 001 or 1 x TFF 524 002
• 1 x ESF 524 001 plus 1 x ESF 524 011
• 1 x TFF 524 002 plus 1 x TFF 524 012
• 1 x ESD 524 003 plus 1 x ESF 524 001 and TFF 524 002

EM 524 regulators are equipped with alarm interface and they can be connected to the BMS control systems.

EM 524 controllers complies the requirements of European standard IEC 60800 1998
