Overview
This manual covers installation of Acrolon's L-1 thermostat., an industrial-grade temperature controller
designed specifically for use wine tanks.
The L-1 should be mounted onto a protective ice shield on the tank and wired to the cooling and/or heating
valves via 16-18AWG 300V wire run inside flex conduit
Key Features:
• Calibration-Free Temperature Sensing
• Two Internal Relays (5A @ 120VAC)
• Easy-to-Use Front anel Controls and Display
• Industrial-Grade ower Line Communications
• NEMA-4X Rated for Indoor and Outdoor Use

TO PRESERVE THE PROTECTION AFFORDED BY THIS E UIPMENT,
CLOSE ADHERENCE TO THE PROCEDURES AND INSTRUCTIONS
CONTAINED IN THIS DOCUMENT IS RE UIRED. FAILURE TO
FOLLOW THE INSTRUCTIONS GIVEN HERE MAY CAUSE FIRE,
PERSONAL INJURY OR VOID OR VOID PRODUCT WARRANTY.

Installation
Mounting:
1. Install the four mounting brackets supplied with the thermostat per Figure 2.
2. Fasten the L-1 thermostat to the ice shield per Figure 3 using four #10 x 3/8” long stainless steel self-
tapping screws. Note that pilot holes might be required depending upon the material used for the ice
shield. Hand tighten each screw to between 8 and 12 inch pounds. DO NOT OVER TORQUE
3. With the thermostat securely fastened to the the ice shield, install 1/2” flexible conduit between the
thermostat's leftmost bottom inlet and the power source. Secure conduit with liquid-tight fittings. See
Figure 1.
4. Fully install temperature probe into thermowell of tank and run the probe cable through the liquid-tight
strain-relief inlet at bottom right of the thermostat. Tighten to 8 and 12 inch pounds or until cable is
secure.

CAUTION: For continued protection against risk of fire, replace only with
same type and rating of fuse.
F3: Little fuse, 218 Series, 6.3A/250V time delay, 5 x 20 mm
F1, F2: Wickmann, TE5 Series, 5.0A Time Delay, short pin
Notes:
1. This product must be connected to mains supply only by permanent field
wiring using the following wire type: THWN, 18 AWG - 250 KCMIL 300 V,
Nylon jacketed w/ high dielectric PVC insulation (UL-83, UL-1063 and UL-
758).
2. All electrical connection and conduits are to be made per National Electric Code
ANSI/NFPA70, or per the applicable code in the country of installation. Use only
conduit and conduit fittings that meet UL 797 safety standard.
3. All wire terminal splice connectors must be UL and CSA rated up to 300 V per UL
486 and temperature rated per UL Flammability UL 94V-2/HB.
This product is intended for use single phase power distribution systems and
relies on the building's installation for short-circuit (over current) protection
and line voltage disconnect. Protective device (circuit-breaker) rating must
not exceed 20 Amps. The installer of this equipment is responsible for
provisioning this circuit-breaker, which must be located in the electrical
distribution panel (breaker-panel) of the building, in close proximity to the
PL-1 thermostat(s) and clearly labeled as being the disconnect for the product.
Compliance is checked by inspection.
ELECTRICAL SHOCK HAZARD: DISCONNECT BREAKERS BEFORE
SERVICING OR INSTALLING THIS PRODUCT!

Internal Wiring (continued)
Mains Wiring:
1. ull one each of the following wires colors from the source power through the conduit to the inside of the
L-1 power supply: GREEN (Earth), WHITE (NEUTRAL), BLACK (LINE), RED (cool output), UR LE
or BLUE (heat output). Leave only enough extra length of wire inside the thermostat to allow for easy wire
preparation and termination. USE ONLY THWN, 18 AWG 300V WIRE.
2. Strip back insulation of each wire 1/8”.
3. Remove the power plug from 1 of the power supply and loosen the all screws terminals.
4. Cleanly install the conductor of each wire into l plug (with no stray strands) per wiring diagram shown in
Figure 4. Tighten the screw terminal as each wire is installed. Torque all screw terminals of 1 to 6 inch
pounds.
5. Install the power plug into the l receptacle on the power supply.
robes Wiring: PL-1 Series II Controllers accept both TankNET -Wire and 2-Wire temperature
probes. Series II PL-1s ship with 2-wire probes unless otherwise requested. Please identify your probe
type as either 2-Wire or -Wire prior to reading and executing these probe wiring instructions.
4-WIRE ROBE WIRING:
1. Strip back insulation of each probe wire 1/8”.
2. Remove the probe plug from 2 of the power supply and loosen the all screws terminals.
3. Install the conductor of each probe wire into the 2 plug per wiring diagram shown in Figure 4, tightening
each screw after installing each conductor. Torque all screw terminals of 2 to 6 inch pounds.
4. Install the probe plug into the 2 receptacle on the power supply.
WARNING: FAILURE TO CONNECT PROPER INPUT VOLTAGE MAY CAUSE FIRE OR DESTROY
PRODUCT AND SHALL VOID PRODUCT WARRANTY!

2-WIRE ROBE WIRING:
1. Install the L-1 thermostat per Acrolon’s L-1 Installation Guide while disregarding the 4-wire probe wiring
information provided with in it.
2. ull approximately 6” of probe cable through the liquid-tight cable gland located at bottom right of L-1
power supply.
3. Strip back the outer jacket of the probe cable about 1” from the cut end of the cable. Take care not to breach
the insulation of either of the two internal wires contained within the cable jacket.
4. Strip back approximately 1/8” of insulation from both the red and black wires of the probe cable.
5. Remove the 4-terminal “ ROBE” plug from the L-1 power supply.
6. Insert the RED wire into the leftmost terminal of the ROBE plug as shown in Figure 1, and secure by hand
tightening the terminal screw using a 4mm x 2.5mm standard screw driver. Insert the BLACK wire into
terminal immediately adjacent to the right of the RED wire per figure below, and secure as previously
described above.
7. If the probe cable has been extended, be sure to use shielded cable and terminate the shield or drain-wire at
J 8 per illustration below.
8. Install the ROBE plug into L-1 display at “J 8” location.
9. Reduce excess probe cable from within the L-1 by pulling the cable back through the cable gland of the
power supply and then tighten the gland to ensure a water-proof seal around the probe cable.

L-1 Display Installation
1. Verify internal power and probe wiring
2. Hold the L-1 display assembly with your right hand with front panel against your palm.
3. Align inside right edge of display assembly with the right edge of the power supply assembly.
4. With your left hand connect the 8-conductor ribbon cable from the power supply to the mating
receptacle on the display assembly (see figure 5).
5. With your left hand connect the 4-conductor ribbon cable from the power supply to the mating connector
on the display assembly (see figure 5).
6. Align the mounting screws of the display assembly with the threaded holes on the power supply
assembly.
7. Using a hillips screw driver tighten each mounting screw starting at upper left, then lower right, the
upper right, and finally lower right. Tightening the LID screws in this fashion prevents binding between
the L-1 display and the power supply. Hand tighten ONLY to 10 to 12 inch pounds.
DO NOT OVER TOR UE.

Applying ower
The L-1 thermostat connects to the mains supply through permanent field wiring via circuit-breaker located in
the electrical distribution panel of the building. This circuit-breaker serves as the disconnect for the thermostat
and should be clearly marked as such in the panel.
Apply power to the L-1 thermostat(s) by switching ON (closing) the corresponding circuit-breaker inside the
distribution panel to which the thermostat is connected. .
