Component listing for integrated systems using Prestyl far‐infrared heating panels

Component listing for integrated systems using Prestyl far‐infrared heating panels.

  1. Far-Infrared Heating Panels: Calculate the appropriate number of heaters required using the Prestyl Transmission calculator.
  2. Select the number of thermostats required.
  3. Calculate the appropriate number of relays using the above calculator (note use at least one relay for each thermostat)
  4. For each system use at least one 24 Volt power supply (to minimize the wiring and related expenses, for larger installations more power supplies may be installed).
  5. For neatness and/or ease of installation the power supply(s) and relays may be installed in an EK‐012 or EK‐024 DIN enclosure (one power supply and up to 6 relays* in one EK‐012 and one transformer and up to 15 relays* in one EK‐024)

Note*: The relay count is valid for Crouzet relays at 120, 208 or 230/240 Volts only, 277 Volt systems use a different relay!

Purchasing info:
 All components identified may be purchased by the installer/distributor or can be purchased through Prestyl USA.
Prestyl USA only carries a very small stock of accessories, if any. If requested, Prestyl USA may purchase the required accessories on behalf of the customer and for this will charge a 20% handling fee. Prestyl USA may help purchase, provide guidance or suggest certain manufacturer’s products as a courtesy only; regardless of who purchases the accessories, Prestyl USA does not warrant any third‐party products!
Furthermore, Prestyl USA is not responsible for the accuracy of third‐party information; the installer should verify that
the correct parts are used in an installation (the installer is responsible for complying with local codes).

  1. Far‐IR Panels. Please order the appropriate size and voltage panels from your Prestyl distributor (120, 208,
    230/240 or 277 Volts).
  2. Select a programmable 24 Volt thermostat with a normally open heating contact (contact closes when heat is needed). Available from many sources including Home Depot, Lowes, etc.
  3. One of the available relays is the “Crouzet DC input contactor”; it can be used with the following voltages: 120 Volts, 208 Volts and 240 Volts. For 277 Volts use an appropriate relay such as Crouzet GNR10DCZ or equivalent (280V, 10 Amps), or GNR20DCZ.
  4. The recommended power supply is a Din‐rail mount power supply: 100‐240 VAC, 24Volt AC out at 1.75 Amps; Possible manufacturer: Phoenix Contact, Part No. 2868648, Mouser part No. 651‐2868648 (the power supply may be powered by 120 volts for all 120, 208 or 230/240 Volt applications or by the panel voltage; for 277 Volt applications the power supply must be powered by a source not to exceed 240 Volts!)
  5. Limited quantities of the EK‐012 or EK‐024 DIN** enclosures may be available at special pricing from Prestyl USA. Similar cabinets may be purchased from a number of sources; one such source is Altech/Els Spelsberg

Note** for 277 Volt relays the EK‐012 or EK‐024 can only be used without the top cover installed; it may be more practical to use a loose DIN rail in a metal NEMA cabinet for mounting the 277 Volt relays
