Zone Valve Control 306V
Introduction
The Zone Valve Control 306V connects up to six thermostats and operates zone valves to provide heating to a zoned
hydronic heating system. The 306V operates a system pump whenever a zone valve opens. Zone 1 can operate either
a zone valve or a circulator to provide heat to an indirect domestic hot water tank with optional priority over zones
2 through 6. The 306V includes optional exercising to prevent circulator seizure when not in use, and optional post
purge operation of the domestic hot water tank to maximize energy savings. The 306V provides a RoomResponse
signal to modulating-condensing boilers to optimize comfort while improving boiler efficiency.

Replacement manuals are available at tekmarControls.com • It is the installer’s responsibility to ensure that this control is safely installed according to all applicable codes and standards. • Improper installation and operation of this control could result in damage to the equipment and possibly even personal injury or death. • This control is not intended for use as a primary limit control. Other controls that are intended and certified as safety limits must be placed into the control circuit. The control includes fuses and transformer that are serviceable. Do not attempt to service any other parts on the control. Attempting to service the control voids the warranty. • Strip all wiring to a length of 3/8 in. or 10 mm for all terminals. • A circuit breaker or power disconnect that provides power to the control should be located nearby and clearly labeled. • Refer to the current and voltage ratings at the back of this manual before connecting devices to this control. © 2019 tekmar 306V _ D - 10/19 2 of 12... -

• 1 Installation and Operation Manual 306V_D • 2 Spare fuses (located in cover) Location • 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. Installing the Enclosure 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. © 2019 tekmar 306V _ D - 10/19 3 of 12... -
