(1
) Split differential for hydronic Target Setpoint e.g. 5.0°C diff = CFH at 2.5°C below Target Setpoint &
CFH end at 2.5°C above Target Setpoint (only available to be viewed/changed if PIM DIP switch 1 is
ON otherwise hydronic differential is 12°C split (6°C above/below setpoint) and parameter is not
displayed
– Default DIP 1 setting is OFF).
