3. All solid state, digital non-programmable, and digital programmable thermostat control sequences except are "continuous fan/valve cycle" only, and are not suitable for use with modulating valves shown in Piping Package Options table. "Fan cycle only" operation is not recommended. Contact factory for "fan and valve cycle" applications.
4. All thermostats ship loose and are furnished with terminal strip connection.

6. All thermostats except T10 include an integral 3-speed fan switch. On DX systems, suction pressure may vary with fan speed, resulting in undesirable operation. Thermostats above do not include an "anti-short cycle" feature typically required for proper DX system operation.
7. Thermostat prices include an aquastat where indicated. Aquastats are sized to match factory piping packages. On units ordered without factory piping package, aquastat furnished is suitable for use with 1/2" piping. Changeover thermostat codes T05, T06, T07, D05, D06, D07, P05 and P06, when ordered with a 2-way piping package, require the addition of a 1/4" bleed line as a Piping Package option.
8. Aquastat is optional on heat/cool changeover units with field supplied thermostats. When ordered with a 2-way piping package, the 1/4" bleed line is also required.
9. Thermostats for Vertical Floor Concealed FCU are available as remote mounted only.
10. Unit mounted thermostats are not available on Vertical Floor Exposed FCU or Vertical Floor Exposed Slope Top FCU with opposite end coil connections.
11. Programmable thermostats must be field configured for the occupied / unoccupied time periods.

DDC Mount & Wire

1. GENERAL
• There is a setup fee per release for all DDC jobs by others, regardless of the number of units. This charge applies only if controls are factory mounted and wired.
• Prices do not include calibration or check-out, which is performed in the field by others.
• Always coordinate with the control supplier and factory prior to giving final pricing and always qualify your bill of material.
• All projects with electric heat must be reviewed by the factory due to space constraints in the Electrical Enclosure/Control Enclosure.
• Extended End Pocket must be included and placed on the control enclosure end on all Vertical Floor Exposed and Vertical Floor Exposed Slope Top fan coil units. See Unit Options table. Four pipe units must have same end connections.
2. TRANSFORMER, FAN RELAY(S), CONTROL COMPATIBILITY
• The factory must supply transformers (if required) on projects with DDC by others mounted at the factory to comply with ETL listings. This is also true with fan relay(s).
• Many DDC FCU controllers do not support three-speed fan control. If three-speed operation is required with these controllers, a manual three-speed switch may be added.
• Most DDC FCU controllers will not support auxiliary electric heat used in conjunction with floating, modulating heat. Always check with applicable controls contractor to see if this combination of control features is supported.
3. All mount and wire orders must be accompanied by a completed Factory Mount & Wire Checklist including all documents listed under Documentation Requirements (with part numbers being supplied by the DDC manufacturer).
4. All mount and wire orders will be subject to the Coordination of Control Shipments to Factory policy.
5. Please advise control suppliers not to make partial shipment and that large orders should be bulk packed when possible.
