Fuses
5amp
, 20mm anti-surge fuse, this fuse supplies power to all
230v outputs from the board, it protects the zone, pump and valve
outputs.
Manifold Pump/Valve
Used for an underfloor heating manifold pump and or valve.
Connections are clearly marked
L = Live
E = Earth
N = Neutral
When an under-floor heating zone sends a call for heat to the
UH8-RF V2, the live & neutral output will supply 230v to the
manifold pump/valve. It is recommended that this is fed through
a high limit switch, placed on the heating manifold to protect
against mechanical failure of the manifolds temperature control.
Zones 1 to 8 Buttons and indicators
Each Zone has an indicator light and button associated with it.
Light functions:
1. Light on when the zone output is on.
2. Light flashes when the zone is in pairing mode.
Button functions:
1. Single press to manually turn output On/Off.
2. Hold down for 5 seconds to start pairing mode, (Indicator steady
flash.)
3. Hold down for 15 seconds to delete pairing, (indicator rapid flash).
System indicators
When lights are on:
1. Dew Point - Informs you that cooling has been
2. Hot Water- Output is On.
3. Pump Output is On.
4. System is cooling.
5. System is heating.
6. Flashes continous in pairing mode (RF Switch Pairing).
Dew Point sensing help to reduce the risk of condensation whilst
cooling is in demand.
When activated, the sensor sends a signal back to the UH8-RF V2,
and will shutdown cooling to the manifold. During this time, the
dew point indicator light will show.
