UFH Pump:
This 230v output is used for an underfloor heating manifold pump.
Connections are marked;
N = Neutral
E = Earth
L = Live
When a zone calls for heat*, the live & neutral output will supply 230v to the manifold pump.
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.
Clamp the insulated part of the cable in the cable grips by pushing upwards.
Bend the pump wires around & first insert the Live wire into the L connection.
Then insert the Earth wire into the E connection.
Next insert the Neutral wire into the N connection, as shown here.
Heat:
This is the voltfree heat output for the system and should be wired to your heat source.
Connections are marked;
LS = Live Supply
LS = Live Supply
LR = Live Return
LR = Live Return
Electrically this is a volt free switch, whatever supply is placed on either of
the LS connections, is fed to the LR connections when there is a call for heat*.
Clamp the insulated part of the cable in the cable grips by pushing upwards.
Bend the wires around & first insert the LR wire into the LR connection.
Then insert the LS wire into the LS connection, as shown here.
*The Heat & UFH Pump outputs are not activated for zone 6 when the switch is set to Rads, explained on page 1.
