General Guide
The following guide illustrates how Wundafloor warm water underfloor heating systems can be coupled together
with the majority of central heating plumbing and control systems.
The majority of modern central heating systems make use of motorised valves, often called Zone valves, to divide
different heating systems and hot water generation ie. Radiators, Under Floor Heating and Hot water cylinder.
Systems using combination boilers will also need zone valves if separate systems of heating require different times
and temperatures.
Quite often ground and first floors are controlled separately as they may have different uses. The zone valve acts
like a relay, meaning any system can call the boiler/ heat source without other areas being activated.
If the underfloor system is being encorporated alongside a radiator system it is even more important that these
areas are controlled independently as ‘heat up’ and ‘cooling off’ times are different. We recommend the ‘S’ plan
layout is adopted as this allows for more variety in zoning, and should be very familiar to qualified plumber/
electricians. The schematics show typical S-plan heating systems with under floor heating encorporated.
NOTE:An Auto By-Pass valve (ABV) should be incorporated in all systems.
NOTE:If a Heat pump manifold has been supplied then there will be no pump on the manifold. Therefore the relay on
the H-Box wiring centre is used to switch on a shunt pump which will send primary water from a
buffer tank or the heatpump itself to the manifolds.
Wundafloor does not supply:• ‘S’ plan wiring centre
• Cylinder thermostat
• Hot water time clock
• Auto bypass valve
Motorised / Zone valves and Pipe stats are available if requested.

This is when a single zone underfloorheating kit is connected to an existingradiator system without an individual zonevalve for the UFH and therefore unable tocall the boiler/heat source independentlyfor heat.
Although a room thermostat or program-mable thermostat can be used to controlair temperature, this area can only be ONwhen the existing heating system is ON.
When this is the case, a pipe thermostatcan be attached to the heating mains flow,so that the new area of the underfloorknows when hot water is available andtherefore stops the pump running when noheat is available.

Section E Installing Wet Room Thermostats
For floor temperature sensing, place probe midway between pipe circuit runs to monitor average floor temperature.
For air temperature, place unit on outside wall of wet room in desired location at height of 1500 mm from floor level.
Check distance between thermostat’s terminal block and probe casing location of wet room’s interior wall is no more than 3 metres.
Do not trim probe sensor to length to ensure the probe wire is long enough to span the distance between the unit’s terminal block, to go through prepared hole through wall and exit into supplied probe housing fixed onto interior wall of wet room at 1500 mm from wet room floor level.
*Bathroom Stat
Unit can be used as a floor temperature sensor or an air temperature sensor.
Bathroom stat on outside of wet room wall
Ensure hole is sealed between wall space and probe housing so that only the wet room air temperature is detected
