Most oil boiler manufacturers do not recommend direct connection to underfloor systems due to wide temperature differentials. CHC recommends using hydraulic separation or a buffer tank to mitigate this issue.
A general rule of thumb is to set the loops between 1 and 2 liters per minute, with higher rates typically applied to longer loops. If a specific design specifies a rate below 0.75, it is recommended to raise it to 0.75 to prevent debris accumulation.
The differential bypass valve controls excess flow in the heating system when zone valves close. It opens at set pressures to bypass water back to the heat source, reducing noise and protecting the pump from wear.
For models like the CHC 414T, with the controller turned off, press and hold the top left corner of the screen for roughly 5 seconds until 'RESET' appears on the display.
