RMU710B / 720B / 730B
Basic type C
= heating / cooling
X = universal input Y = analog output Q = relay output
x = analog or digital a = analog d = digital i = pulse p = switching signal y = positioning signal
= from here
= precommand = start / command = modulating load / output
= checkback signal
= holiday = special day
= 2-position output
Make configuration: From capital to capital letter From small to small letter
Capital letter = physical input or output
Small letter = internal signal
= OR selection = AND selection
= operation selector
