Taco Comfort Solutions 102-067 Timer and Aquastat

Application

The Taco Clock Timer/Temperature Aquastat combination is designed to cycle the circulator during peak demand periods. The Analog Timer (No. 265-1) is adjustable to 15 minute intervals within a 24 hour time frame. The Digital Timer (No. 265-3) can be programmed for 7 day operation. The Temperature Aquastat (No. 563-2) automatically switches the circulator ON at 95ºF and OFF at 115ºF. The two can be used in combination, or they can be used separately. When the Clock Timer/Temperature Aquastat are used together, the Timer switches ON sending power to the unit. The Temperature Aquastat measures the temperature, and cycles the circulator as long as the Timer is switched to the ON mode.
If used separately, the Clock Timer operates the circulator during the chosen number of ON/OFF intervals. When using only the Temperature Aquastat, the circulator cycles intermittently to maintain a temperature between 95ºF and 115ºF. The Clock Timer and Temperature Aquastat are easy to retrofit to any “00” Series Circulator. The user-friendly 24 hour analog clock has an hour hand, raised minute hand for ease of adjustment, two directional arrows, and AM/PM time settings. Our easy to program digital timer provides maximum convenience, comfort and energy savings. The Clock Timer can be mounted in any direction by just attaching it to the capacitor box electrical connection hole.

Troubleshooting

• PROBLEM: Days are flashing, pressing any key does nothing except **key turns output On and OFF.
  SOLUTION:** Time of Day and Day of Week have not been set. See “Setting the Time”. A second, but very unlikely cause of loss of program, is a power failure with the backup capacitor low or dead. Check by disconnecting power and monitoring how long the capacitor keeps the time of day in the display. Typically, the capacitor will maintain the time and programs for 4 days, but not more than 5 days.

• PROBLEM: Time of day was set while holding the key down, but days are still flashing.
  SOLUTION: Current day of week was not set while holding down the ****key. See “Setting the Time”.

• PROBLEM: It is 10 AM and an ON program for 8 AM was entered, but the output is not ON. Display shows the and symbols.
  SOLUTION: After programming, the timer does not “look back” to determine if it should be ON. Press the key (temporary override) to turn the output ON; ****appears in display. The timer will assume automatic operation at the next programmed event.

• PROBLEM: A program for 8 AM Monday thru Friday was entered, but it will not accept it and **is flashing.
  SOLUTION: The ON **or OFF ****was not entered as part of the program. On or OFF must be selected.
