Good morning Yakup.

The best way is to write down how the old t-stat was wired. If that's not available, the only way to determine for certain where each wire goes, is to check what the installer did at the terminals in your home comfort system. Please note the there is high voltage electric in each piece of equipment so if you decide to open up panels, there is always the risk of damaging the equipment or worse, injury or death if you are not a qualified service technician. However, typical color assignments are as follows:
R= (24v from heating appliance) Red
RC= (24v from cooling appliance) Red
These two are only separated when you have two different appliances providing seasonal comfort, like a boiler and an air handler. If you have a warm air furnace with an air conditioner or a heat pump attached then R+RC will have a jumper across them and only one RED wire will be landed there
W= (heat) White
Y= (cool) Yellow
G= (fan) Green
Those colors are pretty standard
The rest of the colors depend on availability in the jacket and are really up to the installer. You mentioned 7 wires but 8 conductors is more likely so I'm assuming the remaining colors are black, brown, blue, and orange.
I always use the following:
C= (common) Black
O/B= (reversing valve for a heat pump) Orange if the valve is energized for heat and Blue if the valve is energized for a/c.
Aux/E= (auxiliary or electric heat) Brown
L= I believe this is a diagnostic terminal for some systems with feedback data and is not used frequently.
After wiring there is some programing to do to set up your new thermostat to your type of system.

Hope that helps. God bless and be careful.

Here is a link, that includes the wiring diagram:

It looks like the 'T-T' terminals match up with 'T-T' terminals on the Boiler Aquastat-- Do you see that control?-- and do you have wires between those controls.
Power to this Control Module is all the way to the left on the connector terminal board-- the ones that say:
R (1) C (2) - Power In

Also: Did you realize that this control is a modulating control-- Not just an 'On-Off' control?
This control has outdoor sensors, that modulate the temperature of the water temperature-- The warmer it is outside, the lower it sets the Hot Water Temperature-- thus saving fuel-- yet assuring that on very cold days, you still get Hot enough water to be comfortable in your occupied space.

On the Protectorelay Oil Burner Control R8184G4009, you connect the two thermostat wires @ "T" and the other "T". On the ACE Smart Temp Universal programable therostat, connect one wire to "Rh" and the other wire to " "W". Be careful if you are using this thermostat for A/C. In that case, make sure there is no jumper between "Rh" to "Rc".

Shut off breaker to you water heater. STILL TEST FOR VOLTAGE BEFORE YOU TOUCH ANY WIRING. The 3 wire that go to you water heater disconnect them. You are going to install them to your WH 40 timer.
The wires that you disconnected will now go to terminals: Black to Terminal 1 & White To Terminal 3, The Ground copper wire will go to the ground terminal should be a green screw.
You will have to buy some 10/2 wiring to go from your timer to your water heater. You can buy it by the foot at Lowes. Figure how much you will need.
With the new 10/2 wire install the Black to terminal 2 & White To Terminal 4, the ground wire will go to the ground screw with the other ground wire.
Wiring that went to terminals 2 & 4 will be installed to you water heater, the same way when you disconnected them. Set your timer clock and your done. Turn breaker back on!
