  • Page 2: Introduction

    ® Whether used stand-alone or networked to a TankNET time. Web Server, the PL-1 thermostat is designed to provide years of reliable and accurate service. Button Hold: To hold a button means to depress the button and to hold it down for a certain period of time.

  • Page 3: Front Panel Layout

    Front Layout Modes Panel Thermostat The PL-1 Thermostat supports the following thermostat modes: COOL Mode - In this mode the thermostat will engage the cooling solenoid via RELAY 1 whenever the cool probe temperature rises above the set point value.

  • Page 4: Thermostat Mode Programming

    Thermostat Mode Programming: Set Point (SET 1) 1. Press and release the SET button as needed to The Set Point (SET 1) parameter is used by the PL-1 advance to mode selection. This is indicated by the thermostat modes as follows: flashing of the currently selected mode annunciator.

  • Page 5: Set Point 2 (Set 2)

    Set Point 2 (SET 2) Temperature Units The Set Point 2 (SET 2) parameter, which is only available in The PL-1 thermostat can be configured to display AUTO mode, determines the temperature below which the temperature values in either Celsius or Fahrenheit.

  • Page 6: Probe Display

    Probe Alarms (“P1A” and P2A”) The PL-1 thermostat supports up to two X-Bus™ The PL-1 includes two probe alarm enables, one for each temperature probes and allows the operator to toggle probe that can be attached to the thermostat. A value of between the two probe temperature readings.

  • Page 7: High Alarm (Al - )

    High Alarm Threshold (“AL ”) Low Alarm Threshold (“AL_”) This parameter determines the probe temperature above This parameter determines the probe temperature below which an alarm will be triggered. which an alarm will be triggered. Programming: Programming: To adjust the high alarm temperature threshold for the To adjust the low temperature threshold for the selected selected probe alarm: probe alarm:...

  • Page 9: Pump-Over Duration (Pod)

    Pump-over Duration (“Pod”) Control Configuration (“CC”) This parameter is used to determine how long (in minutes) This parameter is used to grant access to the advanced the thermostat will wait before resetting the Pump-over state thermostat configuration parameters. from “On” to “OFF”. Programming: The unit of measure for this parameter is minutes.

  • Page 10: Thermostat Differential (Dif)

    Thermostat Differential (“diF”) Units Lock (“UL”) This parameter determines the thermostat switching This parameter can be used to prevent inadvertent changes differential (or hysteresis), which applies to all thermostat to the local temperature display units setting. When this modes. parameter is set to “On” the thermostat’s temperature units can not be changed locally.
  • Page 11 Cool Probe (“CP”) Heat Probe (“HP”) The PL-1 thermostat supports two temperature probes. The The PL-1 thermostat supports up to eight temperature Cool Probe (“CP”) parameter tells the thermostat which probes. The Heat Probe (“HP”) parameter tells the probe to use for cooling. Only those probes which are thermostat which probe (or sensor in the case of a ®...
