Each Event Start Time is preset with 1 minute resolution.

1) Event Start Time

Option 1SPDT1PR :

Toll Free: 1-866-829-4253

All programming is done with the Hand Held Remote Control ( included ).
Each Event is programmed separately and consists of the following values :

The Mutli-Event Thermostat operates in the background and the Clock Time, Date, Weekday, Month and Year can be still displayed in any mode, as set-up by the user. The clock can be synchronized to any Master clock or can be set-up to be the Master for other Slave clocks.

2) Event Target Temperature

Each temperature is programmed with 1 deg. F ( or 1 deg. C ) resolution within the range from - 40F to +255F ( or - 40C to +124C ) .

NOTE:
The Mutli-Event Thermostat is NOT sensitive to the power interruptions. Even after the power absence for longer periods of time, the programmed schedule will be executed withour error, as if the power was present all the time.

3) Programming of Temperature Limits and Heat / Cool Auto Change-over

The thermostat may be programmed with temperature limits that will prevent oveheating or overcooling even if the target temperature is set outside the limits.

In the AUTO mode the automatic change-over temperature points may be programmed to switch automatically between the heating and cooling.

For the MANUAL mode the target temperature may be programmed in advance for fast override of the AUTO mode with the MANUAL mode.

Option # 713 :
For manually preset Heating Control and Alarm with 1 or 2 external probes.

Option # 714B :
For Heating or Cooling up to 32 events per day, separate for each of the 7 days of the week

Option # 714C :
For Heating and Cooling ( AC ) up to 32 events per day, separate for each of the 7 days of the week
and with Auto Change-Over for Heat / Cool

NOTES :
1) The Temperature Sensing probe wiring may be extended up to 500 feet ( 150 M ) with any type of a 2-conductor cable.
2) Terminal block on the back panel for wiring to the probes and to the internal relay contacts. Load up to 10 Amp, 250Vac.

Temperature Probes and Sensors ( for options # 711, 712, 713, 714B and 714C )

The temperature monitoring, programmable thermostat and control options require an internal or external temperature sensor probe. The standard sensor normally included with the selected option may not be the most suitable model for each application and therefore a specific probe model may be ordered.
The selection below shows some of the available models and mounting accessories.
NOTE, that the probe wiring may be extended up to 500 ft ( 150 m ) with any type of a 2-conductor cable.
