4.3 FLOW SWITCH
The Hurlcon Boiler has an inbuilt flow switch which allows the burner to operate only when the system is
full of water and the circulating pump is operating. NOTE: The installed flow switch has no user
adjustments.
Air in the system may stop the boiler from lighting.
4.4 GENUS IV 3 BUTTON CONTROLLER
90° or 55° operation
. HW series boilers are factory default 90°. For floor heat applications the boiler can
be selected for 55° max setpoint by a jumper on the PCB. (See page 16).
Hurlcon Genus IV room thermostat.
If a Hurlcon Genus IV room thermostat is fitted the Genus boiler
control will
‘learn’
automatically when powered up, after approx 1 minute. If the thermostat is disconnected
or loses communication F5 fault will be displayed and the boiler will shut down after 3 minutes. To change
thermostat type see table below. The thermostat selector switch located on the „heatsaver‟ PCB also
needs to be set to the correct position for pump run on. See page 16, 90 degree operation.
Switching differential.
The temperature switching differential can be adjusted to stop short cycling. See
table below for appropriate codes. (Default 5°.)
°F or °C.
The display can be toggled between Celsius and Fahrenheit. See table below for codes.
(Default °C.)
With the unit switched off, press and hold the on/off button then press the following.
