When a cycle starts under a high heat latch, it will finish the heating cycle on high stage.

On — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all heating demands.

Default is OF (off).

Option 24 — Programmable/Non−Programmable

This selection allows the installer to configure the thermostat as either programmable or non−programmable. Selections are P, nP.

Default is P (programmable models only).

Option 25 — Number of Programmable Periods

This selection allows the installer to configure the thermostat for two or four periods per day. Two periods is a common commercial application and four periods is more common for residential. This selection is not available if Option 24 has been set to nP to configure the thermostat for non−programmable operation.

2 — Periods DAY and SLEEP are available

4 — Periods WAKE, DAY, EVE, and SLEEP are available. Default is 4.

Option 26 — Minimum Cooling Setpoint

This selection allows the installer to configure the minimum cooling setpoint that the user is allowed to set. The range is based on the value of the adjustable deadband Option 11, such that the minimum of the range is 50_F/10_C plus the adjustable deadband and the maximum is 90_F/32_C.

Default is 52_F/11_C (based on the adjustable deadband default = 2).
