3 Front Panel Layout Thermostat Modes 1 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 1 rises above the set point value. 2 HEAT Mode - In this mode the thermostat will engage the heating solenoid (selectable between RELAY 1 and RELAY 2) 2 whenever the heat probe temperature 3 falls below the set point value. AUTO Mode - In this mode the thermostat will automatically switch between HEAT and COOL modes as required. The following are the salient parameters and operating characteristics of AUTO mode: Legend: LCD display window 2. SERVICE LED used to indicate network configuration status 3. SET Button - used to enter and exit programming mode and to advance through thermostat parameters 4. DOWN Button - used to adjust thermostat parameters 5. UP Button - used to adjust thermostat parameters RELAY 1 is always used for COOLING RELAY 2 is always used for HEATING Set Point (SET 1) is the COOLING set point Set Point 2 (SET 2) is the HEATING set point HEATING and COOLING functions are mutually exclusive, with COOLING taking precedence over HEATING. In other words, should conditions be such that the criteria for both heating and cooling are met simultaneously, the thermostat will engage only the cooling relay and not the heating relay. OFF In this mode all thermostatic operation is disabled as are all alarms. Additionally, when operating in a TankNET server environment, data logging and alarm notifications for the thermostat are also disabled See COOL PROBE ( CP ) parameter 2 See HEAT RELAY ( Hr ) parameter 3 See HEAT PROBE ( HP ) parameter - 4 -

6 Probe Display The PL-1 thermostat supports up to two X-Bus temperature probes and allows the operator to toggle between the two probe temperature readings. Probe Alarms ( P1A and P2A ) The PL-1 includes two probe alarm enables, one for each probe that can be attached to the thermostat. A value of On enables alarms (high/low and probe fault) for the selected probe. A value of OFF disables alarms for the selected probe, regardless of the values assigned to that probes high/low alarm threshold parameters. Alarms are indicated locally via an ALARM annunciator and remotely via in TankNET server environments. Probe 1 Alarms ( P1A ): Probe 2 Alarms ( P2A ): On / OFF On / OFF 1. Press and release SET button until the PROBE annunciator flashes. 2. Press the UP or DOWN button to toggle between the available probes. 3. Hold the SET button to exit programming mode OR press and release the SET button again to advance to the next This setting is only in effect during programming mode. During normal operating modes probe temperatures are displayed per the following: In COOL and AUTO modes the temperature of the designated Cool Probe ( CP ) will be displayed. In HEAT mode the temperature of the designated Heat Probe ( HP ) will be displayed To enable or disable temperature alarms for a given probe: 1. Press and release the SET button as needed to advance to the P1A or P2A the UP/DOWN buttons to adjust the parameter to the desired value

7 High Alarm Threshold ( AL -- ) This parameter determines the probe temperature above which an alarm will be triggered. Low Alarm Threshold ( AL_ ) This parameter determines the probe temperature below which an alarm will be triggered. To adjust the high alarm temperature threshold for the selected probe alarm: To adjust the low temperature threshold for the selected probe alarm: 1. Press and release the SET button as needed to advance to the AL -- parameter for the desired probe the UP/DOWN buttons to adjust the parameter to the desired value 1. Press and release the SET button as needed to advance to the AL_ parameter for the desired probe the UP/DOWN buttons to adjust the parameter to the desired value This parameter is only accessible when the corresponding probe alarm is enabled (PxA = On, where x = probe number). This parameter is only accessible when the corresponding probe alarm is enabled (PxA = On, where x = probe number)

8 Brix Entry ( Br ) The Brix entry screen allows Brix measurements taken at the tank to be entered directly into the thermostat. In TankNET server environments, Brix measurements entered at the thermostat are recorded into the TankNET database and are available in the form of fermentation graphs via the Web. Pump-over Entry ( Po ) The Pump-over event entry screen allows cellar crews to enter pump-over events at the thermostat. In TankNET server environments, pump-overs are viewable on both the winery maps and on the fermentation graphs via Web Browser. Valid range: -9.9 to 50.0 NULL value: = Press and release the SET button until the BRIX annunciator flashes 2. Use the UP / DOWN buttons to adjust the parameter to the desired value 1. Press and release the SET button until the Po the UP/DOWN buttons to adjust the parameter to the desired value Note: The pump-over entry feature is designed for minimal user interaction. Cellar staff need not remember to change the pumpover state from On to OFF after completing a pump-over operation. Instead, the thermostat will automatically change the pump-over state from On to OFF as determined by the default pump-over duration. See Pump-over Duration ( Pod ) for more information about this mechanism

9 Pump-over Duration ( Pod ) This parameter is used to determine how long (in minutes) the thermostat will wait before resetting the Pump-over state from On to OFF. The unit of measure for this parameter is minutes. Control Configuration ( CC ) This parameter is used to grant access to the advanced thermostat configuration parameters. 1. Press and release the SET button until the Pod the UP/DOWN buttons to adjust the parameter to the desired value (in minutes). Note: Setting this parameter to zero (0) disables the automatic pump-over shut off feature and will require cellar staff to manually turn pump-overs ( Po ) OFF. 1. Press and release the SET button until the CC menu indicator is displayed. 2. Press the UP or DOWN button to turn this menu ON 3. Press and release the SET button to advance to the first control configuration parameter. Note: This parameter is reset to OFF upon exiting programming mode. This parameter is only accessible while Po is set to On

10 Thermostat Differential ( dif ) Units Lock ( UL ) This parameter determines the thermostat switching differential (or hysteresis), which applies to all thermostat modes. This parameter can be used to prevent inadvertent changes to the local temperature display units setting. When this parameter is set to On the thermostat s temperature units can not be changed locally. 1. Press and release the SET button until the Dif the UP/DOWN buttons to adjust the parameter to the desired value. 1. Press and release the SET button until the UL the UP/DOWN buttons to toggle this parameter between On and Off

11 Cool Probe ( CP ) Heat Probe ( HP ) The PL-1 thermostat supports two temperature probes. The Cool Probe ( CP ) parameter tells the thermostat which probe to use for cooling. Only those probes which are attached to the thermostat can be assigned to the Cool Probe parameter. The PL-1 thermostat supports up to eight temperature probes. The Heat Probe ( HP ) parameter tells the thermostat which probe (or sensor in the case of a Stratiprobe ) to use for heating. Only those probes which are attached to the thermostat can be assigned to the Heat Probe parameter. 1. Press and release the SET button until the CP the UP/DOWN buttons to toggle this parameter between the available probes. 1. Press and release the SET button until the HP the UP/DOWN buttons to toggle this parameter between the available probes

12 Heat Relay ( Hr ) Heat-Modes Disable ( Hd ) This parameter determines which of the two internal relays will be engaged for heating. This setting only applies to HEAT mode and has no effect in COOL and AUTO modes. This parameter can be used to prevent the thermostat from being set to any of the heating modes. When this parameter is set to 1 only COOL and OFF modes are allowed. 1. Press and release the SET button until the Hr the UP/DOWN buttons to toggle this parameter between the Relay 1 and Relay Press and release the SET button until the Hd the UP/DOWN buttons to toggle this parameter between the 0 (allow heat mode) and 1 (disable heat mode)

13 Data Entry Disable ( ded ) Power Up Delay ( Pud ) This parameter is used to disable brix and pump-over data entry at the thermostat. Setting the value of this parameter equal to 1 disables brix and pump-over entry. The factory default value of this parameter is 0 (brix and pumpover data entry enabled). This parameter is used to delay thermostatic operation for a pseudo-random period of time immediately following power up. Setting this parameter to a value of 1 inhibits thermostatic operation for a period of between 240 and 320 seconds at power up. Setting the Pud parameter to a value of 0 (factory default) disables this delay function. A countdown timer (in seconds) is displayed while thermostat delay is in effect. Pressing any front panel button during the count down will cancel the delay and cause the thermostat to resume normal operation. 1. Press and release the SET button until the ded the UP/DOWN buttons to toggle this parameter between the 0 (brix and pumpover entry enabled) and 1 (brix and pumpover entry disabled). 1. Press and release the SET button until the Pud the UP/DOWN buttons to toggle this parameter between the 0 (no power delay) and 1 (delay at power up)

14 Show OFF ( SoF ) Network Service Function The value of this parameter determines whether the thermostat displays probe temperature or the text OFF in the LCD window when the thermostat is in the OFF mode. A value of 1 causes the thermostat to show OFF while in OFF mode. A value of 0 (factory default) causes the thermostat to display probe temperature while in OFF mode. 1. Press and release the SET button until the SoF the UP/DOWN buttons to toggle this parameter between the 0 (show probe temperature) and 1 (show OFF ). + The SERVICE function is primarily used to register the thermostat with a TankNET server during network installation. Once registered, the thermostat can then be monitored and controlled via the TankNET Web Software. The SERVICE function also contains an LED, which is used to indicate the network configuration state of the thermostat. The typical network configuration states are: 1. Unconfigured (factory default): In this state the Service LED will flash ON and OFF at a rate of approximately 1.5 hertz (times per second). This state is normal for thermostats that have not yet been registered with a TankNET server. 1. Configured: In this state the Service LED will remain dark. This state is normal for thermostats that have been registered with a TankNET server. Uninstalling a Thermostat: The SERVICE function can also be used to remove a thermostat from a TankNET network. CAUTION: This operation will cause the thermostat to become inaccessible from the TankNET Web Software. To remove the thermostat from an existing TankNET network, hold down both the SET and UP ARROW buttons simultaneously for approximately 10 seconds For non-networked environments in which the flashing SERVICE LED may be undesirable, a jumper is provided inside the thermostat (J5) to disable SERVICE LED activity. IMPORTANT: THIS JUMPER SHOULD REMAIN IN THE ENABLED POSITION FOR NETWORKED THERMOSTATS

15 External Wiring Internal Cable Connections Notes: A) Maximum wire gauge per contact = 16 AWG. B) Jumper required (as shown) for switched leg A standard PL-1 thermostat has two internal ribbon cables that must be connected during installation. These cable connections are shown below. When installing, snap each cable into its mating connector to ensure a reliable connection

16 Fuses and Service The PL-1 thermostat has been designed to provide years of reliable service in harsh cellar environments. In the unlikely event that you do experience a problem with your thermostat, please contact Acrolon technical support for assistance via or support@acrolon.com. The PL-1 thermostat contains three internal fuses, which are located on the power supply assembly. Under normal operating conditions these fuses should remain intact. However, it is quite common for a solenoid failure (usually a shorted coil) to cause the corresponding relay fuse to fail (open). In such cases, no energy will be transferred to the solenoid when the relay is engaged. IMPORTANT! USE ONLY SPECIFIED FUSES FOR REPLACEMENT RISK OF ELECTRIC SHOCK! BE SURE TO DISCONNECT POWER AT THE SOURCE BEFORE OPENING THE THERMOSTAT FOR ANY REASON! Main Fuse (F3) Littlefuse P/N HXP Relay 1 Fuse (F1) Wickmann P/N Relay 2 Fuse (F2) Wickmann P/N
