In an asassinish sort of way. If you do find a door please let me know. I need one for a yta1a2b1-cf c. Originally Posted by supertek Originally Posted by chillerguy Please read this Valves, Regulators, Filters, Etc.

All times are GMT In addition, this screen allows manual control of the frequency command being sent to the Variable Speed Drive. Displays a value based on the pressure differential between the Evaporator and Condenser pressures.

Allows manual programming of the command frequency value. Manually programming this value will put the VSD frequency control into manual mode.

Following manual programming of the command frequency, this returns the system to automatic control. It will not raise the value above the maximum allowed frequency. This key puts the vane control into manual mode and sends a HOLD command to the contacts. Displays the time remaining in the minute manual oil pump operation described below. The Oil Pump is limited to running for a maximum of ten 10 minutes. If a longer running time is desired, this key must be pressed again. Manual Oil Pump control is disabled and the button hidden during system prelube, system run and system coastdown.

This screen displays all information pertaining to an Electro-Mechanical Starter. Indicates whether the digital output from the controls is commanding the motor to RUN. Displays the current limit value in use. Displays the time remaining in the programmed pulldown period if the value is non-zero.

Allows the user to specify the maximum allowed motor current as a percentage of FLA. When the motor current reaches this value, the pre-rotation vanes will not be permitted to open further. If the motor current rises above this value, the pre-rotation vanes will close to reduce the current to this value.

This value will override the Motor Current Limit value during this time period. This function is used to provide energy savings following chiller start-up. Allows the user to set a period of time for which the pulldown demand limit will be in effect after the chiller starts.

Display the 3-phase input line voltage values being read from the Solid State Starter. Display the 3-phase motor current values being read from the Solid State Starter. Displays the current limit in use. Displays the Solid State Starter model that is applied to the chiller.

Allows the user to specify the maximum allowed motor current as percentage of FLA. When the motor current reaches this value, the Pre-rotation Vanes will not be permitted to open further. If the motor rises above this value, the Pre-rotation Vanes will close to reduce the current to this value.

Displays the cumulative amount of kilowatts used over time as the VSD motor controller operates. Allows the user to reset the cumulative Kilowatt Hours. Only 2 available when chiller is stopped.
