• 40 Multi-day ON/OFF or signal operations per channel, per week
• Astronomic Capability on any or all channels
• LCD readout displays scheduling instructions in everyday English
• Remote manual timed override requires only single momentary contact pushbutton – may be set from
1-255 minutes timed ON and may be pushed again to terminate
• Duty cycle ratio from 1-99 minutes with nine different patterns
• Staggered start feature
• Conventional AM/PM or 24 hour format
• Daylight Saving – automatic or user defined dates
• Leap year – automatic adjustment
• Safety override switch for each channel
INSTALLATION:
The following instructions must be followed to assure proper controller program functions:
• The Controller is to be installed where temperatures will remain between 32-120 degrees Fahrenheit. For
trouble-free operation, it should not be exposed to mechanical vibrations, dusty conditions, corrosive
sprays or condensing humidity.
• Controller relays are plug-in type; SPDT dry contacts (unpowered) with LED indication when N/O
contacts are energized. Contacts are 10 AMP @ 120VAC/240VAC/28VDC and 1/3 HP @ 120VAC.
• To install unit, open front cover, remove (2) screws on right side of inside front panel and swing panel to
left. Locate upper screw keyhole and two lower screw holes.
• For convenience, mount unit so LCD display is at eye level and fasten with #10 sheet metal screws or
other suitable fastening devices.
• Connect 120VAC(*) power (dedicated), SEE DIAGRAM INSIDE FRONT DOOR. POWER FEED IS
BROUGHT TO RIGHT HAND CORNER TERMINAL BLOCK.
• CONNECT LOAD WIRES to lower terminal board. LED will light indicating “ON” between C and N/O, if
programmed to be
ON or by manual override. See Figure 2 as typical.
• If remote override is to be used, connect remote override (2 wires per channel for appropriate loads) to
terminal block in top left side inside panel. Use a momentary push-button (bell-type button) — one wire to
load, one to common.
DO NOT CONNECT ANY POWER TO THESE TERMINALS.
• When unit is first powered battery is not connected. The unit will prompt you to PRESS BATTERY
SWITCH — THEN PRESS ENTER.
• Locate the slide switch next to battery on circuit board (see drawing located inside front door) and slide it
left into the ON position. Return inside front panel to proper position and fasten with screws. Then
PRESS ENTER button. The model number will first be displayed. Verify that it matches the model
number on your unit. If not, call TORK.

* For -2 use 240VAC 50/60HZ. Not UL and CSA approved.
1. Make sure unit is grounded (earth ground).
2. If remote overrides are used, make sure these unpowered wires are not run in the same conduit as
the load wires or supply voltage for the controller.
3. Controller must have its own dedicated 120VAC(*) power source; i.e., NO OUTLETS OR OTHER
LOADS ATTACHED TO THE SAME SUPPLY SOURCE COMING FROM YOUR BREAKER PANEL.
