If you have 2 hot wires, then you have 240Volt circuit from breaker box.
T8845PV is 120Volt timer.
How to wire for 120Volt: Use one hot wire to connect to LINE terminal. Cap off other hot wire. Then connect bare ground wire to terminal marked NEUTRAL.
This is not code, but it will work until you have time to run 120Volt line from nearby 120Volt outlet.
Read about 120 and 240Volt circuits
http://waterheatertimer.org/B220C.html

T8845PV is 120Volt timer, made to control 24Volt sprinkler valve.
Inside the timer, there are two wiring terminals marked LINE and NEUTRAL
120Volt cable from circuit breaker has black hot wire and white neutral wire.
Connect black hot to terminal marked LINE
Connect white neutral to terminal marked NEUTRAL

The yellow wires are 24Volt output.
Yellow wires connect to sprinkler valve.
Do not connect 120Volt to yellow wires.
This timer does not have terminals for rain sensor:

T8845PV has 2 yellow wires for 24Volt output that powers solenoid.
1) Yes the yellow wires connect to two wires on solenoid.
2) 120Volt power arrives from breaker box. Black hot wire connects to Line terminal screw. White neutral connects to Neutral terminal screw. Check for 120Volts across both terminal screws.
3) Next check that output on yellows wires is 24Volts. The manual does not specify if that is 24Volt AC or DC. I assume that means it is AC. Buy cheap multimeter at home center to check 24Volt output.
4) Tests from 2) and 3) will tell you if 120V circuit is problem or if transformer has gone bod or if solenoid is suspect.
5) T8845PV uses T8845PV transformer, but it might be cheaper buying whole new timer and then snapping new mechanism into existing box

How do I install a T8845pv sprinkler timer. What do I attach to the two yellow wires


http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/t8845pv%20-%20english.ashx

The timer is used to power a low-voltage sprinkler solenoid valve.
A solenoid is an electrical switch that opens and closes a gas line or water line.

The yellow wires go to your sprinkler system solenoid valve.
The solenoid is the valve that turns water on-and-off.

The 120Volt electric cable that runs the timer connects to the Line and Neutral terminals.
Black to Line terminal, white to neutral terminal

The clock repeats each 24 hours.
Lift and rotate dial until current time lines up with silver pointer

The skipper wheel has pins >> press pin down for each day you do not want watering
Rotate skipper wheel counterclockwise until current day lines up with 14 arrow

Put tripper pins on yellow dial
Each pin represents 12 minutes of watering
To water for 48 minutes, put in 4 consecutive pins
Put pins on wheel at the time you want watering to take place.
To water twice a day, put pins at two different times, and do not put any pins between those times.

H20 ERROR SPIN DRYING


The error indicates a problem with the incoming water supply.
Check for restricted or kinked inlet hose/s, check that tap/s are fully turned on and that you have adequate water pressure.
