1 Installation, Wiring and Controls for STEP Warmfloor 1

2 What We Learned From Previous Webinars How to sell the STEP Warmfloor product through reliability, energy efficiency, simplicity and safety The many applications that are available to utilize the product to gain more revenue for your business How floor covering and insulation have an effect on performance and meeting customers expectations Dennis 2

3 Planning Your STEP Warmfloor Installation Review the worksheets and layout diagram Understand there is a limitation on secondary wires lengths Determine Transformer and thermostat location Determine type of control or regulator 3

4 Planning Your STEP Warmfloor Installation Insure materials used with installation are compatible Follow local codes and manufacturers instructions Use components recommended by manufacturer 4

5 STEP Warmfloor Components Thermostat Power supply Heating element 5

6 EPI-LX Thermostat Series EPI-LX-TH Non-programmable 15 minute heating cycles Air and/or floor temperature sensing EPI-LX-SEN EPI-LX-THPR Programmable 15 minute heating cycles Air and/or floor temperature sensing EPI-LX-SEN 6

7 EPI-LX Sen Temperature sensing only - not a high limit sensor! A mode controls ambient air temp F mode- utilizes floor sensor, thermostats ignores air temperature AF Mode- monitors air and floor temperatures Installation note Run sensor wire through conduit and place between heating elements 7

10 Control Options Micro Program controller Line voltage Time controller Small applications On/Off switch Switches primary supply voltage Utilize in bathrooms. 10

11 Benefits of the STEP Power Supply Designed to be easy to install and fit in wall cavity Trusted, refined, and perfected regulation technology Maximizes energy efficiency of the STEP Warmfloor system ETL Approved 10 years warranty 11

12 The STEP Power Supply Rating of the STEP Power Supply The primary voltage is 120, 208 or 240 VAC The secondary voltage is normally 24V. The transformer has circuit breakers on the primary and on the secondary. 12

13 EPI-LX-R Power Supply Series 13

14 EPI-LX Power Supply Energy Efficient Toroidal Coils Benefits of toroidal coils Toroidal coils with winding built around ring-shaped core creates minimal mechanical hum Toroidal coils are more efficient (100%) Low exterior magnetic field 14

27 Installation of STEP Warmfloor system require specific wires and connectors to comply with the ANSI/UL approval EXTENSION WIRE Extension wire for field wiring from power supply to elements #14, #12 or #10 AWG stranded tinned copper CONNECTOR & TAPE Tinned copper crimp connectors Insulating electrical moisture sealant tape CRIMP TOOL Used to crimp CON-DB crimp connector. TOOL-PRO ratchet crimp tool is required as it is specially designed to properly crimp CON-DB crimp connector. 27

28 Connect Elements Cut the bus braid, exposing 1 of bus braid Connect bus braid to extension wire (PVC copper tinned 105 wire only) with crimp. Tape connectors Differentiate polarities of wire using black and white conductors 28

29 Connecting the elements 29

30 Connecting the elements 30

31 Securing the Element Wood subfloors - staples or nails every 2 feet, keeping element flat Hot melt glue- quarter size every 2 feet, keeping element flat Thin Set- industry methods Self leveler-industry methods 31

33 Wiring Options Elements are connected in parallel do not exceed 225 Watts. The elements can be wired directly to the interface board on the transformer Each design quote distributes evenly the load from the elements to each circuit breaker: EPI-LX-500VA = 2 connection s@ 225W EPI-LX-1000VA = 4 connection s@ 225W EPI-LX-1500VA = 6 connection s@ 225W Terminal block(s) may be needed if the transformer is a long distance from the elements. Maximum total load per circuit is 450 Watts. 33

36 Polarity of Element Layout 36

37 Terminal Block For long wiring distance between transformer and element The heating elements can be routed directly to the transformer or if needed to a terminal block All wires to the elements in the floor must be PVC insulated, stranded, tinned copper, minimum #14AWG (2mm 2 ) Use 10 ga wire or larger conductor to transformer depended upon distance and load (watts) Each T-Block can handle 450 watts 37

38 Fail Safe Wiring This method avoids the elements to short out and is used for installations that are not embedded in concrete or leveling compound and for between joist applications The heating elements can be routed directly to the transformer or if needed to a terminal block All wires to the elements in the floor must be PVC insulated, stranded, tinned copper, minimum #14AWG (2mm 2 ) 38

39 Document Your Work Take pictures Mark wires with element number (s) Complete warranty forms and forward to manufacturer or distributor Apply caution labels to electrical panel Enjoy a lifetime of comfort and efficiency 39
