Optional — Three-Button Wired Remote Control (133PE1484A)
The Three-Button Wired Remote Control (133PE1484A) plugs into either the 
Three-Circuit Clock (PE1353ME) or Valve/Pump Switch (PE4243ME). 
When installed as part of a system, it replaces the wireless method of controlling 
the three circuits within the mechanism. For more information, refer to Installing a 
Wired Remote Connection in Section 4. The Three-Button Wired Remote Control 
must be installed where a third mechanism is needed in the enclosure box, since the Wireless 
Hand-Held Transceiver can only control two mechanisms.
Optional — Freeze (Air Temperature) Sensor (178PA28A)
Add the Intermatic Freeze or Air Temperature Sensor (178PA28A) to installations 
where below-freezing outdoor temperatures are a concern. Programming 
information to incorporate the sensor is provided on page 34.
