SOURCE: I have an MTD8 timer, that fits into my main electrical board

MTD8 Timer - Instruction manual

1. This timer has a total of 8 ON / OFF programs.

2. MANUAL ON / AUTO / MANUAL OFF for easy setting.

3. Switchable 12 / 24 hour mode.

4. 16 timer combinations are available as follows:

Monday

Tuesday

Wednesday

Thursday

Friday

Saturday

Sunday

Mo, Tu, We, Th, Fr, Sa, Su

Mo, Tu, We, Th, Fr, Sa

Mo, Tu, We, Th, Fr

Mo, We, Fr, Su

Mo, We, Fr

Tu, Th, Sa

Mo, Tu, We

Th, Fr, Sa

Sa, Su


Initial operation:

1. When the timer is first connected to mains power, it will take up to 12 hours to charge the internal battery.

2. The settings can be defaulted by depressing the R (reset) button.


Setting Current Time.

1. Press the C+ (clock) button and hold, then simultaneously press the W+ (week) button until the actual day is displayed. Continue by pressing the H+ (hour) or M+ (minute) button until the current hour or minute is displayed. When setting, the W+, H+ and M+ buttons can be held down for rapid forward counting.

2. Release both buttons. The weekday and time will be set according to your selections.

3. To set incorrect time (etc.) repeat the settings.


Settings for programs:

1. Press the Timer button (Clock) and release. The first ON setting can now be made.

2. Press the W+ button to set the day or blocks of days. Select the ON time by pressing the H+ button and then the M+ button.

3. Press the Timer button (clock symbol) again to finish the first ON setting and enter into the first OFF setting. Repeat step 2 to set the first OFF setting.

4. Press the Timer button again to finish the first OFF setting and enter into the second ON setting. Repeat steps 2 and 3 to program the remaining settings.


When setting block dates, the ON and OFF times apply to all dates in the block.

I.E. Selecting block Mo, Tu, We, Th, Fr, Sa, Su and setting ON to 10:00 and OFF to 16:00 means that the selected times automatically apply to all the indicated days in that block.


Specifications: 230Vac 50 or 60Hz. 16A Inductive load. 20A Resistive load.

Battery backup >100 hours. Accuracy: +/- 1 minute per month. Temp: -10 to +40 deg C.

How to set a Kes load control timer model ISG1201


The Geyser Load Control Timer, ISG1201, is designed to prevent geyser from operating during the Eskom's designated weekly morning and evening peak times. The ISG1201 features 4 easily selectable, pre-programmed, geysers "ON" operating profiles to ensure maximum comfort whilst not burdening the user with the complicated process of having to program the unit.
The profiles are as follows;
  • Program (1) is always "ON"
  • Program (2) "ON" after sunset to accommodate solar geysers
  • Program (3) "OFF" all the time
  • Program (4) savings program - "ON" 6 hours weekdays and 12 hours weekend days

Geyser timer stopped working


Check circuit breaker.
Click fully off and then back on.
Check for burned smell at breaker or loose crackling sound that says breaker is bad.

Reset timer. Then Reprogram.
Possible geyser timer manual
http://waterheatertimer.org/pdf/Digital-Geyser-Timer 24H-7-Day-Timer-230V Brochure.pdf

This timer has a non-replaceable internal rechargeable battery.
If battery has gone bad, then timer is defunct.

Use manual override button to turn timer ON-OFF.
Then test across terminals 3 and 4 for 240Volts.
Turn timer OFF, and test across terminals 4 and 5 for 240Volts
If no voltage shows then timer does not have output.

If test shows 80% undervoltage, that can cause load not to activate, depending on type of load.
Have electrician check for voltage issues at power company transformer.

Unknown what load timer is connected to.
Max load for this timer at 240 volts is 3680 watts, 16 amps.
Motor load is 230 volt 8 amps.
Check label on load for watt or amp rating.
Volts x amps = watts
Watts divided by volts = amps

How to bypass mtd8


To permanently bypass the timer, you have to move wiring.
I don't have specific wiring diagram or programming manual for mtda8 timer, but am familiar with wiring din-rail mounted digital timers.

1) Wiring is typical across all din-rail timers, with variations of same theme depending on number of channels and purpose.
2) Open following illustration of wiring:
http://waterheatertimer.org/images/DIN-series-wiring-300.jpg
Same-similar illustration shows on side of timer.

3) Notice the mtda8 has 5 screw terminals.
4) Two screws are for incoming power. These terminals are usually labeled 1 and 2. These wires power the timer.

5) Three more screws are for the timing relay. These screws are usually labeled 3 4 and 5.
Typically the #4 center screw is common, and carries power. And when timer is ON, power is live between #4 and #3 terminal. When timer is OFF, power is live between #4 and #5 terminal.

6) Move #3 wire to #4 or #5 screw and then the timer function is bypassed.
