Caleffi 663 Series 3 Outlet Distribution Manifold Assembly
Pre-Assembled distribution manifold: Includes Return distribution manifold With Built-In Shut-Off Valves suitable for thermo-electric actuator and Supply distribution manifold With manually adjustable Balancing Valves. Available with either 1" or 1-1/4" NPT inlet ball valves. 3/4" outlets. Loop Cv: 2.3. MAX working pressure: 150 psi. MAX temperature: 210 FDistribution manifolds for radiant panel systems are used to optimally distribute the heating fluid in floor heating system circuits and ultimately improve the control of heat emission from the panels. The manifolds ensure that the flow of each circuit is regulated precisely and also control the shut-off, venting and automatic removal of air from the system.$229.65 -

Azel I-Link SZ-V6 Zone Valve Controls
Azel 6 Zone Valve Controller with Priority. Unlimited Zone Expansion.The i-Link series Zone Valve Controls simplify the field wiring and yet control up to six zone valves in a multi-zone hydronic heating system. The contractor friendly Printed Circuit Board eliminates the problem caused by incorrect wiring and saves hours of installation time. There would be no more “messy” look of conventional zone valve installations.
Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers. Field selectable priority with Priority Protection Timer ensures other zones get heat every one hour and prevents freeze-ups in the event of a priority zone failure. The End Switch delay timer let the two wire type zone valves fully opened before turning on the circulator. The panel provides EZ screwless terminal blocks for connections to the thermostats and zone valves. In addition, LED indicators on the front panel provide functional status and easy troubleshooting.

Tjernlund MAC-4E
Enables Appliances to be Interlocked in Conjunction with UC1 universal controlThe MAC4E is used in conjunction with the UC1 Universal Control to interlock up to four additional 24 VAC, 115 VAC or millivolt (Dry Contact) controlled appliances. It activates the Venter through its connections to the UC1 and in turn relies on the UC1 Fan Prover safety circuit (P1 & P2) to allow its interlocked appliances to operate. Any pre/post-purge settings on the UC1 will be defaulted to the MAC4E. Two LEDs for each appliance interlock block are provided on the MAC4E. LEDs #1, 3, 5, 7 (AMBER) shows an appliance call for heat. LEDs #2, 4, 6, 8 (GREEN) shows that the burner is approved to fire after the Venter Fan Prover safety circuit through the UC1 is completed. The MAC4E also has an LED #9 (RED) which means power is supplied to the MAC4E through the UC1.$596.00 -
