Step 4 — Attach Thermostat Ends Once you have connected the new wire or wires to the furnace terminals, return to the thermostat and remove the wire from the pencil. Transferring heat from a hotter to a cooler tank in order to equalize the temperature in both tanks and increase total storage capacity is another common use for a differential controller. The wires are totally interchangeable. It is very useful in radiant zones that have more than one heat source. As the name implies, this relay activates a pump or pumps when a span or difference between two temperatures is achieved. Repeat the replacement process for the W wiring to complete connection for any W2 wiring if necessary. What matters is the difference between the water temperatures at the two locations.
A multi-zone controller may contain from two to six relays, but the wiring procedure stays consistent. This field lets you decide when to shut your pump off. To us, removing a banana from a bunch of six, leaves five bananas. When the tank temperature drops to whatever set point you decide, a circulator pump turns on and draws heat from a heat exchanger. The Delta T is the difference between the temperature at your solar collectors and the temperature at the bottom of your storage tank.
This function protects air conditioning compressors from over-cycling and is useless for radiant heating purposes. Things to Consider Check to make sure the house wiring to the thermostat is smaller than those connected to the house electrical outlets. If you are careful and follow the instructions, you can save a great deal of money by wiring yourself. Any thermal storage medium can be heated in this manner, including hot tubs, greenhouse growing beds, aquariums, worm farms, towel warmers…. Based on whatever parameters you set, the storage tank draws the heat it needs from the heat exchanger to maintain a constant tank temperature.
The circulator pumps are wired to the lower, high voltage terminals for zones 1, 2, 3, etc. Toggle up or down to your desired temperature differential. The wires are totally interchangeable. Use the down arrow to set this function to 0 zero. A row of orange tabs along the top of the controller panel allow you to insert the thermostat wires and a block of terminal screws along the bottom labeled N neutral and L load make wiring each zone pump very easy. Step 2 — Disconnect Wiring Remove the electric power supply wiring from the back of the thermostat. The rest of the fields fit into this category and are useful for specialty applications.
This function protects air conditioning compressors from over-cycling and is useless for radiant heating purposes. Therefore, we recommend that you use this page and the accompanying photo to make the process quick and simple. The lines from the power source circuit panel are connected to N common and L hot. Compare Reznor Gas Unit Heater models, specs and prices. But, as soon as the colder fluid in the loop circulates passed the sensor, it cools down again. These terminals do not send any voltage to the boiler. After all, if the water is actually hotter than what the sensor indicates, so much the better.
When the Delta T is reached, the Resol controller activates the solar pump and circulates heated fluid from the solar collectors. This controller can also be used in reverse. Expect the solar pump to short cycle until the water in the overall collector loop heats up. This power wire is necessary to complete a two-stage firing of the furnace. The factory installed jumper is not moved. The reason is because, early in the morning when the sun starts warming the collectors, most of the fluid in the collector loop is still cold.
If the wires are not color coded to the new thermostat, mark each one noting which terminal to which they were attached. You may even want to go higher. Remove the old wire and attach the new to the furnace terminal for the white wire. Robert Shaw brand thermostat If you have the Robert Shaw brand thermostat, use the following schematic. Learning how to wire your heater thermostat to your furnace will help you save on professional electrician charges. A quick start wiring guide for multi-zone systems. Of course, the i-Link controller can also be wired for special applications and the most common ones are illustrated below.
If the wires to the thermostat are large like outlet wires, you will need to have these replaced from the power source to the thermostat location. If your thermostat was located on a wall without a stud, make sure to use drywall anchors to secure it properly. Consult with our experienced Reznor Gas Fired Unit Heater experts. Special Wiring Diagrams for the i-Link Controllers Certain situations require the i-Link controller to do more than simply activate a circulator pump every time a zone calls for heat. However, once the sun hits the panels, the fluid at the top of the collector, nearest to the collector sensor, warms up quickly and triggers the system.
The factory default setting is 140-degrees. Either that, or a branch from an existing circuit can be run to the controller box. In other words, when the temperature at the solar collector is X degrees hotter than the temperature at the bottom of the solar storage tank, the differential controller activates the necessary pump s and draws that useful heat into the system. Instead, it functions very much like a standard, low voltage wall thermostat — it connects to a relay, which in turn powers the circulator. The boiler itself contains a transformer that is activated whenever this circuit is closed.
This operates the furnace fan blower. We offer unlimited technical support ~ toll free 866-warm toes 927-6863 Basic single zone controller So…. Wiring the Thermostat Honeywell Pro 1000 Thermostat 6 terminal The Pro Th1000 is a versatile, multi-functional thermostat, and very easy to use and wire. This setup would be useful for a system using an outdoor wood boiler connected to a continually active heat exchanger. Red or White can go to either terminal. In other words, the controller is nothing more than three radiant floor zones, activated by three thermostats. Step 6 — Place on Mounting Plate Replace the mounting plate by sliding on the wall stud choosing a different hole location.
