 | Works with compressor controller's Energy Miser™ to raise suction pressure when loads are
light, saving energy. |
| Allows fan cycling for energy savings when possible. |
| Controls up to 8 evaporator zone temps and defrost sequences. |
| Displays 8 evaporator zone return air temps. |
| Displays 8 evaporator liquid line temps. |
| All defrost parameters are password protected, individually selectable for each zone. |
| Defrost start time is determined by amount of time the liquid solenoid is energized
since last defrost. |
| Defrost stop time is determined by hot gas exit temp plus variable time delay, backed up
by adjustable maximum time period. |
| Allows shutting down neighboring evaporator during defrost. |
| Defrost Blackout Table defines time when defrost is not allowed for each evaporator
on a seven day basis. |
| Displays run time percent usage status for each evaporator. |
| Can be operated in heating mode for dock heating. |
| Logs run time hours for each evaporator. |
| Allows individual time offset of zone temp set points. |
| Logs all defrosts. |
| Limits number of evaporators defrosting at same time. |
| Defrost control scheme greatly reduces energy usage over standard time-clock systems. |
| Controls liquid solenoid, hot gas solenoid, suction stop valve and bleed valve. |
| Simple change of evaporator control parameters. |
| Two-speed fan version is also available (2S2T8) |
| Variable-speed fan version is also available
(2T8V) |
| 3T8 version is also available, which is identical to 2T8, except it also measures discharge air temp, allows defrost
initiation based on air temp drop, with cumulative cooling time backup. |
