Single Zone System
A single zone system with a single thermostat (4, 6, or 8
loops) is used when the heating
requirement is uniform throughout the structure. Typical
applications: homes, offices, cafeteria, hotel lobbies,
gymnasiums, factories, heated warehouses,
aircraft hangers, nursing homes, childcare centers,
If the heating requirement is not uniform, such as a living
room, garage, basement, sauna/pool room, up to four single zone units may be supplied by
the same heat source to meet the heat load and
temperature requirements within the structure.
Principles of Operation
When the thermostat
temperature drops below set point the circulator is
activated. All loops will be
supplied in the WarmmFloors heating system. When set point is reached,
the controller turns off
the circulator and stops flow through the loops.
If an area is heated
manual valve may be used to shut of a loop.
The liquid level must be at or above
the tank level marking. When liquid level is too low, an audio alarm will sound
and disable (protect) the circulator.
Primary Loop - Single Zone
- First Floor Layout
Commercial and Industrial applications:
• Child Care Centers
• Hotel Lobbies
• Factory Buildings
• Heated Warehouses
• Aircraft Hangers
• Nursing Homes
Principle of Operation
A single heat source may be used to provide the
heating for single or multiple levels.
The primary loop temperature may be controlled to
limit the energy allocated for each zone.
If any thermostat calls for heat, the respective
thermostat will activate the circulator and disperce
the heat. If an area needs not to be heated (accupants
option) a manual hand valve may be installed to
reduce or eliminate heating in the respective area.
Any number of thermostats (zones) may be calling for
heat and draw heat from the primary loop until the
desired room temperature is reached and maintained.
The heat source is sized for the combined heat load
for all zones.
The energy allowed for each may be limited by the
heat source temperature that is controlled and
proportioned to the outside temperature. The primary
loop must me designed to maintain a min flow
velocity of 2’/sec. to transport any air trapped in
The heat source shall have
the following specification:
1 - Expansion Tank
2 - Automatic System Pump for make up water
3 - Liquid Make Up Tank with Low Level shut down and
4 - Automatic Vent - Terminating into the make up
