These can be used to simplify programming. All times must be the same for the days chosen!
Let us say you want to run a device Monday through Friday at the same time. Scroll down to #9
and you will have the days set!
Press the “TIMER” key and the display will show “1ON--:----” set the time you want the unit to
turn on by pressing the “HOUR” and “MIN” buttons respectively. To set the turn off time, press
the “TIMER” key again and “1OFF--:----” will show in the display. Again, set the “HOUR” and
“MIN” time. If you want more than 1 on/off per day, press the “TIMER” key again and set
“2ON--:----,” “2OFF--:----” until you reach the maximum of 8 on/off’s per day.
The timer is now set, but you need to push the “MANUAL” button until the line is under “AUTO.”
If you only want 1 on/off per day or if you have more on/off’s per day, when you are done
programming them in, press the “CLOCK” key again and you are almost done. The timer is now
set, but you need to push the “MANUAL” button until the line is under “AUTO.”
Reset the setting: If you wish to change any or all on/off times, you must reset the timer. You
cannot change just one setting.
Clear all: To erase all settings, Press the button.

FIGURE 3.1.1 SL70 SCHEMATIC
FIGURE 3.1.0 EV90, EV90P, EV130, EV200, EV240, AND EV300 SCHEMATIC
NOTE: There is a
wire on the TC7D
that connects
Terminal 1 to the
relay common of the timer.
You must cut this wire to
eliminate voltage to
relay common.
In this example, the timer turns the Energy Recovery Ventilator (ERV) on at High speed when the
timer dictates it is an occupied time.
Operation Modes:
There are three operation modes: “ON,” “AUTO,” and “OFF”; selected through the “MANUAL”
key. When the “MANUAL” key is pressed, observe that the indicator (line) on the screen moves
upon the words.
uMODE ON: When the indicator is on “ON,” the output turns on immediately and keeps this
status while in “ON” mode.
uMODE OFF: When the indicator is on “OFF,” the output turns off immediately and keeps this
status while in “OFF” mode.
uMODE AUTO: When the indicator is on “AUTO,” the output turn on and turn off based on
the programs.
When the timer is not powered, it turns off the output permanently.

In this example, the ERV does not run while unoccupied, set by timer. During occupancy,
ERV runs at variable Speed. CO2 Controller sets speed based on CO2 levels. Remove the
potentiometer(s) by cutting the wires at the potentiometer. Cap the orange and purple wires
from the potentiometer with wire nuts. EV450 Circuit Board shown with one potentiometer.
HE1X and HE1.5 Circuit Board has two potentiometers and the cut wires can be wired in parallel
back to the CO2 Controller.
