Timers
Timers controlling pool equipment are necessary to manage energy usage and control that equipment operates in the correct sequence. Typically pump, cleaners, SWGs, heaters, and lights may be controlled by internal timers or external timers. Pool Automation Controllers can provide the timing and control of most pool equipment. Where equipment does not have an internal timer, or connected to automation, then an external timer is used.
Intermatic Timers
Intermatic[1] external timers are often used in pools and spas.
The Intermatic T100 Series of timers are mechanical with a 24 hour yellow dial that uses moveable trippers to set multiple ON and OFF times.
Key differences in the T100 Series models are:
- Clock motor voltage
- Switch type
- Single Pole single Throw - SPST
- Double Pole Single Throw - DPST
- One Normally Open, One normally Closed Contacts - NONC
- Enclosure type
- Outdoor Type 3R Metal (R)
- Outdoor Type 3R Plastic (P)
Popular Intermatic models are:
- T101 - SPST with 120V clock motor
- T103 - DPDT with 120V clock motor
- T104 - DPDT with 240V clock motor
- T106 - NONC with 240V clock motor
SPST timer can switch a single 120V hot line DPDT timer can switch two independent 120V hot line or the two hot lines for a single 240V device.
T1XX models with a M suffix are mechanism only and can used to replace the timer in an existing enclosure.
The T1XX timers have a manual level below the clock dial that can be moved left or right to turn the power ON or OFF. Moving the lever will not effect the next operation of the trippers.
Heater Control
The T101 or 104 timers can have an optional 156T4042A Heater Control Switch Kit that will open the fireman's switch on the heater 20 minutes before the timer, usually controlling the filter pump, will shut off. The heater control will prevent the heater from operating EXCEPT when the Time Switch contacts are closed (automatically or manually).
Models that have the 24-Hour Mechanical Time Switch in Enclosure with Pool Heater Protection are:
- T101P201 - 120V SPST plastic enclosure with Pool Heater Protection
- T101R201 - 120V SPST metal enclosure with Pool Heater Protection
- T104P201 - 240V DPST plastic enclosure with Pool Heater Protection
- T104R201 - 240V DPST metal enclosure with Pool Heater Protection
Mechanical Timers with power Centers
Intermatic has a line of power centers that have one or two timers in an enclosure to meet different needs. One of the more interesting combinations is the T10604R | 30 A Power Center with T106M & T104M Mechanisms[2] that can be used to control two speed pumps. .
