* Chiller Nameplate RLA MUST match chiller dataplate per compressor.
T
Determines when to shut off a compressor. ONLY applies to multi-chiller setup.
M
Inhibits loading if LWT change exceeds the setpoint value
M
Additional compressor can start if LWT change is below setpoint
M
Time period to go from initial load point (% RLA) set in SP5 to 100% RLA
M
Initial amps as % of RLA, Uses SP4 & 6
M
Soft load on or off, Uses SP6 & 7
T
T
% RLA above which loading is inhibited (Load Limit) SP + 5% unloads compressor
T
% RLA below which unloading is inhibited
ON sets %RLA at 0% for 4 mA external signal and at 100% RLA for 20 mA signal
O
M
