5Model: UH8-RF V2
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.
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.

shut off to prevent condensation.
Engineers test switches
These are a block of 12 dip switches, used to test each zone,
boiler, pump and HW outputs. To enable any output, put the
switch in the ON position. When installation is complete all
switches MUST be in the OFF position.
Record the rooms names connected to each zone with the
zone number and record the channel number you have
selected, you will need this information when installing the
thermostats.
