• For engineered/natural timber floor finish only:
o Prior to laying floor covering, a liquid leveller/screed layer is required
o Liquid leveller/screed (the main brands) used must be compatible with floor heating
o The layer must be a minimum of 10 ml thick to ensure flooring does not become void of warranty
from floor manufacturers
• Additional care should always be taken when working over floor heaters
• It is recommended that a piece of cardboard or carpet is used to temporarily cover the heaters to avoid
accidental damage to the heaters while laying floor covering in other areas
• If the monitor sounds an alarm:
o Stop work immediately and check monitor connections (see page 7)
o If connections are secure but alarm still sounding, then check the heater element and insulation
resistance
o Test yourself if you have a multimeter, otherwise contact Coldbuster or your electrician.
• A flexible cement-based tile adhesive and grout suitable for floor heating must be used – contact a floor-
tiling supplier for advice if uncertain of the adhesive type
• If tiles require lifting during tiling, to avoid point pressure of lever trowel damaging the heater element:
o Slide a trowel under tile
o Slide a second trowel between tile and first trowel and lever tile up
• Do not allow any heavy or sharp objects to fall, stand upon, run over or be dragged across exposed
heating elements
o Place buckets of tile glue on a piece of hardy sheet to protect the element from the weight of the
bucket
o Do not use an angle grinder to create expansion joints
• For tile finish only:
o Grout tiles as soon as possible according to the adhesive manufacturer's guidelines
o Do not turn heaters on until tile adhesive has cured in accordance with adhesive & grout
manufacturer's guidelines (usually about 7 days)
IMPORTANT: The monitor will detect damage to the element needing to be repaired immediately (if
there are cuts to the element). Bruising damage will only manifest at 240V. An insulation (Megger) test
by an electrician is recommended.
Thermostat Fit off & Connection to Mains Power
• IMPORTANT: THESE STEPS MUST BE DONE BY A LICENSED ELECTRICIAN
o Check thermostat instructions for wiring details
o All heaters must be connected to RCD protected supply circuit
• Disconnect monitor from heater before connecting heater and floor sensor to thermostat and
thermostat to mains
• Multiple heaters must be connected in parallel
• Use of the floor sensor is optional but recommended
• The floor sensor is essential when the thermostat is mounted inside a cupboard/vanity or outside
the area being heated (air sensor won't pick up correct temperature)
• Remember:
o These are double insulated devices – there is no earth connection to the thermostat
o The earth of the heater connects directly to the earth of the supply in a screw connector
