UH6 Explained
Mains Supply
Power supply into the UH6 which should be fused
at 5 amps these connections are marked
L = Live or phase 230v AC 50/60Hz
E = Earth
N = Neutral
When powered on, the power light will be green.
Fuse
5 Amp, 20mm anti-surge fuse.
This fuse supplies power to all 230v outputs from the UH6.
The fuse also protects the zone & pump outputs.
When the fuse is blown, the Fuse LED will light Red.
To replace the fuse, remove the fuse holder,
replace fuse & re-insert fuse holder.
Heat
This is the main call for heat for the system,
there are 4 connections;
LS = Live Supply
LS = Live Supply
LR = Live Return
LR = Live Return
Electrically this is a volt free switch, The supply placed on
the LS connection, is fed to the LR connection when
there is a call for heat.
Delay Setting Switches
Heat & UFH Pump delay
When there’s a demand it is possible to set a timed delay, before activating
the Pump & Heat* outputs.

*Heat Output Delay
This determines if the HEAT output is affected by the delay configured on
switches 1 & 2.

4 = On 4 = Off

3 = On 3 = Off
Creepage Function
During hot weather the heating may not be required as often, which means
after long periods of the UFH pump not being used, the pump can seize and
refuse to operate.
1 Minute 2 Minutes 3 Minutes
1 = On, 2 = Off 1 = Off, 2 = On 1 = On, 2 = On

To prevent this, it is good practice to operate the pump once a day, the
creepage function does this for you. Once enabled the UH6 will operate the
pump for 1 minute, only if the outputs have not been operated by a
thermostat, within the preceding 24 hours.
This function does not operate the HEAT output.
