SL Wireless Control Heating System

Our SL Wireless Control Heating System provides building owners or operators a variety of heating control options through four different wireless controllers connected to one or multiple SL heaters.

The SLPB, SLVT, SLVTB and SLTI single zone wireless controllers have been developed to make installation and setting up easy, and are compatible with a wide range of SL heaters including low surface temperature heaters.

The SLPB, SLVT and SLVTB controllers feature a 4-stage run-back timer function where the heating period will stay active until the run-back timer expires. The SLTI controller, on the other hand, has a programmable 7-day timer with 3 heating periods per day.

The SL heating system is suitable for domestic and commercial premises such as homes, student accommodation, hotels, modular buildings and offices.

Run-back timer for controlling energy costs

The 4-stage run-back timer function in the SLPB, SLVT and SLVTB controllers allows the heating to be active for a time period selected by users making it ideal for areas such as hotels or student accommodation.

Users can activate the heating using the pre-set time segments set by the building owners or operators. There is a choice of three time segments available: 5, 15 or 30 minutes. When the main control button is pressed four times, this takes the run-back time period to 20, 60 or 120 minutes.

  Button press x 1 Button press x 2 Button press x 3 Button press x 4
Time segments (minutes) Heating period (minutes) Heating period (minutes) Heating period (minutes) Heating period (minutes)
5 5 10 15 20
15 15 30 45 60
30 30 60 90 120

Below illustrates how the run-back timer works on our three controllers.

SLPB controller

Example of the SLPB run-back timer active with four 15-minutes time segments selected by user.

Temperature set at 21°C by building owner. User is unable to set temperature on the SLPB controller.

SLVT or SLVTB controller
