NOTE:

An HP temperature sensor must be used with a heat pump

application using electric strip heat. This is necessary in case the
DTO is set to the Off position.

Timeguard

The WeatherMaker Two-Zone provides equipment protection with
an internal 5-minute timeguard delay. This delay is present upon
initial power up. There is also a 5-minute timeguard delay for all

cooling (Y1) and heat pump modes. The time guard can be cleared
by using the comprotec override feature. Second-stage (Y2) and
(W2) will have a 5-minute delay between stages and also can be
cleared using the comprotec override feature.

Maximum Cycle Rate

The WeatherMaker Two-Zone will allow a maximum of 4
equipment cycles per hr or 1 every 15 minutes when a heating or
cooling mode is activated. When a demand exists, and internal
