Radio Frequency Interference

Installation

The installer must ensure that this control and its wiring 
are isolated and/or shielded from strong sources of 
electromagnetic noise. Conversely, this Class B digital 
apparatus complies with Part 15 of the FCC Rules and 
meets all requirements of the Canadian Interference-
Causing Equipment Regulations. However, if this control 
does cause harmful interference to radio or television 
reception, which is determined by turning the control 

off and on, the user is encouraged to try to correct the 
interference by re-orientating or relocating the receiving 
antenna, relocating the receiver with respect to this control, 
and/or connecting the control to a different circuit from 
that to which the receiver is connected.
Cet appareil numérique de la classe B respecte toutes 
les exigences du Règlement sur le matériel brouilleur du 
Canada.

Installing the Enclosure

•  tekmar or jeweler screwdriver
•  Phillips head screwdriver

•  Needle-nose pliers
•  Wire stripper

•  18 AWG LVT solid wire (low-voltage connections)
•  14 AWG solid wire (line-voltage connections)

•  Four 1/8” - 1” wood screws

•  1 Zone Valve Control 305V
•  2 Spare fuses (located in cover)

•  Installation Manual 305V_D

•  Keep the control dry. Avoid potential leakage onto the control.
•  Maintain relative humidity less than 90% in a non-condensing environment.
•  Avoid exposure to extreme temperatures beyond 32-122°F (0-50°C).
•  Install away from equipment, appliances, or other sources of electrical interference.
•  Install to allow easy access for wiring, viewing, and adjusting the display screen.
•  Install approximately 5 feet (1.5 m) off the finished floor.
•  Locate the control near pumps and/or zone valves if possible.
•  Provide a solid backing which the enclosure can be mounted to. Example: plywood or wall studs.
•  Use the conduit knockouts provided on the upper, lower, and back of the enclosure for wiring.

To prevent the risk of personal injury and/or 
death, make sure power is not applied to the 
control until it is fully installed and ready for 
final testing. All work must be done with power 
to the circuit being worked on turned off.
Please be aware local codes may require 
this control to be installed or connected by 
an electrician.
